For most late-model truck owners who tow or haul, I’d start with the PowerStop Z36 Extreme Truck & Tow K2164-36 because it covers front and rear brakes and is built around heavy-use driving. The Detroit Axle kit for 2020–2024 Silverado and Sierra HD is a more vehicle-specific option, while the GM 10/12 Bolt rear disc kit suits owners upgrading the rear brakes on select classic C10/C15 trucks. The main tradeoffs are axle coverage, exact vehicle fit, and whether you need a complete front-and-rear package or a focused replacement. A larger or more extensive kit is not automatically the right choice if it does not match your truck’s year, axle, and brake configuration. Read on for how these six options differ and which buyer each one suits.

Key Takeaways
- Fitment divides this group: the GM rear disc kit targets specific 1963–1970 C10/C15 6-lug applications, while the Detroit Axle kit is listed for 2020–2024 Silverado and Sierra 2500/3500 HD trucks.
- Several PowerStop Z36 kits cover both axles: K2164-36, K2813-36, and K8171-36 are front-and-rear pad-and-rotor packages, but their distinct part numbers mean buyers must confirm exact application rather than assume interchangeability.
- K137-36 is the focused option: its front-only coverage may suit a front brake refresh, but it does not replace a full front-and-rear kit when both axles need service.
- The classic-truck kit serves a different purpose: the GM 10/12 Bolt kit is a rear disc conversion for specified older trucks, not a direct alternative to complete modern truck pad-and-rotor packages.
- Package coverage matters as much as the truck-and-tow label: confirm included components, axle coverage, and fitment details before comparing kits or planning installation.

More Details on Our Top Picks
GM 10/12 Bolt Rear Disc Brake Kit, 63-70 C10/C15, 6-Lug, Standard, No E-Brake
For a 1963–1970 GM C10 or C15, this kit offers a focused rear-disc conversion rather than a broad front-and-rear refresh. Its 6-lug fitment suits trucks retaining that wheel pattern, making it a more relevant choice for a classic build than the modern-truck kits here. Unlike the PowerStop Z36 K2164-36, it is not a complete four-wheel pad-and-rotor package, so buyers should plan around the truck’s existing front brakes and verify axle compatibility. The main compromise is explicit: no e-brake is included. That can mean sourcing additional parking-brake parts and checking local requirements before installation. I’d shortlist it for a targeted vintage-truck conversion, but skip it if you need a complete system or want parking-brake components in the box.
Pros:- Application is specifically listed for 1963–1970 GM C10/C15 trucks.
- 6-lug configuration targets a defined classic-truck setup.
- Rear-disc format suits a focused axle conversion rather than requiring a full brake-system replacement.
Cons:- No e-brake is included, so additional parts may be needed for parking-brake function.
- Fitment is limited to specific classic GM applications and must be checked against the truck’s configuration.
- Does not include the front-and-rear pads and rotors supplied with the PowerStop Z36 K2164-36.
Best for: Owners converting a 1963–1970 GM C10 or C15 with a 6-lug setup who want a rear-disc upgrade and can source parking-brake parts separately.
Not ideal for: Buyers who need an included e-brake, a complete front-and-rear brake package, or a kit for a truck outside the listed years and models.
- Application:1963–1970 GM C10/C15
- Brake position:Rear
- Kit type:Disc brake conversion kit
- Lug pattern:6-lug
- E-brake included:No
- Kit designation:Standard
Our verdict“Choose this kit for a compatible vintage C10/C15 rear-disc conversion only if you have a separate plan for the e-brake.”
PowerStop Z36 Extreme Truck & Tow Front and Rear Brake Pad and Rotor Kit K2164-36
The Z36 Extreme Truck & Tow K2164-36 is the most complete match here for owners of compatible Ram or Dodge applications who want front and rear friction parts replaced together. It includes four drilled and slotted rotors, carbon-fiber ceramic pads, and installation hardware, while the rotor coating is intended to resist corrosion. That makes it a broader service package than the front-only PowerStop Z36 K137-36, which leaves the rear brakes untouched. The tradeoff is fitment: this kit is for select Chrysler Aspen, Dodge Durango, Dodge Ram 1500, and Ram 1500 Classic models, not trucks generally. The supplied details describe towing and severe-duty use, but they do not make this a larger-rotor big-brake conversion. I’d favor it for a compatible truck needing a coordinated four-wheel refresh, not for a buyer seeking a universal upgrade.
Pros:- Includes front and rear pads, four rotors, and stainless-steel installation hardware.
- Carbon-fiber ceramic pads are described as quiet and low-dust.
- Drilled and slotted rotors are designed to manage heat during towing and heavy-duty driving.
- Silver Zinc Dichromate rotor finish is specified for corrosion resistance.
Cons:- Fitment is limited to select listed Chrysler, Dodge, and Ram models and requires vehicle confirmation.
- This is a pad-and-rotor replacement kit, not a larger-diameter big-brake conversion.
- Components may arrive in multiple boxes.
Best for: Owners of listed Aspen, Durango, Ram 1500, or Ram 1500 Classic models who tow or haul and want pads and rotors for both axles in one kit.
Not ideal for: Drivers with unlisted vehicles, buyers seeking a larger-caliper or larger-rotor big-brake conversion, or anyone replacing only the front brakes.
- Brand:PowerStop
- Model:Z36 Extreme Truck & Tow
- Part number:K2164-36
- Fitment:Select Chrysler Aspen, Dodge Durango, Dodge Ram 1500, and Ram 1500 Classic models
- Included components:Front and rear brake pads, 4 drilled and slotted rotors, installation hardware
- Pad material:Carbon-fiber ceramic
- Rotor finish:Silver Zinc Dichromate
- Warranty:36 months or 36,000 miles limited
Our verdict“Pick the K2164-36 for a compatible Ram or Dodge that needs a complete, towing-oriented front-and-rear brake refresh.”
PowerStop Z36 Truck & Tow Front and Rear Brake Pad and Rotor Kit, K2813-36
This PowerStop Z36 front-and-rear kit brings together carbon-fiber ceramic pads, four drilled and slotted rotors, and installation hardware for compatible trucks and SUVs. Its appeal is the coordinated four-wheel replacement: compared with the front-only PowerStop K137-36, it addresses both axles, while the K2164-36 has a more specifically stated Chrysler, Dodge, and Ram fitment list. The K2813-36 description gives a broader vehicle category but no exact applications, so buyers need to confirm the part against their vehicle rather than assume a general truck fit. The coated rotors are described as helping resist rust and corrosion, and the pads are designed for quiet stopping. It is still a replacement pad-and-rotor package, not a larger-caliper big-brake conversion. I’d choose it when verified fitment and a complete axle-to-axle refresh matter more than a stated model list.
Pros:- Provides pads and rotors for both front and rear axles.
- Includes installation hardware alongside the brake components.
- Carbon-fiber ceramic pads are designed for quiet stopping.
- Drilled and slotted rotors have Silver Zinc Dichromate plating to help resist corrosion.
Cons:- The supplied fitment information does not identify exact makes, models, or years.
- It is a pad-and-rotor kit, not a caliper or larger-rotor conversion.
- Components may arrive in multiple boxes.
Best for: Truck and SUV owners who have confirmed K2813-36 compatibility and want pads, rotors, and hardware for both axles.
Not ideal for: Buyers who cannot verify exact vehicle fitment, need a model-specific application listing before purchase, or want a true larger-rotor big-brake conversion.
- Model:PowerStop Z36 Truck & Tow K2813-36
- Fitment:Compatible trucks and SUVs; confirm vehicle fitment
- Included components:Front and rear brake pads, 4 drilled and slotted rotors, installation hardware
- Pad material:Carbon-fiber ceramic
- Rotor design:Drilled and slotted
- Rotor finish:Silver Zinc Dichromate plating
- Warranty:36 months or 36,000 miles limited
Our verdict“Choose the K2813-36 when you have verified compatibility and want a matched four-wheel Z36 pad-and-rotor refresh.”
Detroit Axle Brake Kit for 2020-2024 Chevy Silverado and GMC Sierra 2500/3500 HD
For a 2020–2024 Silverado or Sierra 2500/3500 HD with single rear wheels, this Detroit Axle kit is the clearest heavy-duty-specific fit in the group. It pairs front and rear drilled and slotted rotors with ceramic pads, then adds brake fluid and cleaner, making it a more extensive service bundle than the PowerStop Z36 K2164-36. The listed rotor sizes—13.98 inches front and 14.17 inches rear—give buyers useful scale information, though the product data does not establish an upgraded rotor size over factory equipment. Its 10-year warranty is longer than the limited warranties listed for the PowerStop kits. The tradeoffs are substantial package weight and narrow fitment: it is specified for single-rear-wheel models, not every HD configuration. I’d put it first for the named late-model HD trucks, but not for dual-rear-wheel owners or shoppers seeking a proven big-rotor conversion.
Pros:- Fitment specifically covers 2020–2024 Silverado and Sierra 2500/3500 HD single-rear-wheel models.
- Includes front and rear drilled and slotted rotors and ceramic pads.
- Brake fluid and brake cleaner are included with the brake components.
- The listed 10-year warranty exceeds the stated warranty periods of the PowerStop Z36 kits.
Cons:- Single-rear-wheel fitment excludes dual-rear-wheel configurations.
- At 146 pounds, the package calls for suitable handling and installation support.
- The supplied data does not establish that the rotors are larger than the vehicle’s original equipment.
Best for: Owners of 2020–2024 Chevrolet Silverado or GMC Sierra 2500/3500 HD single-rear-wheel models who want a front-and-rear service kit with fluid and cleaner included.
Not ideal for: Dual-rear-wheel HD owners, drivers of other model years, or buyers who need confirmation of a larger-than-stock rotor or caliper upgrade.
- Fitment:2020–2024 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD, single rear wheel
- Front rotor size:13.98 inches (355 mm)
- Rear rotor size:14.17 inches (360 mm)
- Rotor design:Drilled and slotted, front and rear
- Pad material:Ceramic
- Included components:2 front rotors, 2 front pads, 2 rear rotors, 2 rear pads, brake fluid, brake cleaner
- Warranty:10 years
- Item weight:146 pounds
Our verdict“Choose this Detroit Axle kit for a listed single-rear-wheel Silverado or Sierra HD when you want a bundled four-wheel brake service rather than an unverified big-brake conversion.”
PowerStop Z36 Truck & Tow Brake Pad & Rotor Kit Front K137-36
The PowerStop Z36 K137-36 is the focused choice for Toyota owners who need front brakes for towing or hauling but do not need a four-wheel kit. It includes two carbon-fiber ceramic pads, two drilled and slotted rotors, and installation hardware for the listed 4Runner, FJ Cruiser, and Tacoma applications. Compared with the front-and-rear PowerStop K2813-36, this package covers only the front axle, which avoids buying rear components when they are not due for replacement. The tradeoff is equally clear: it cannot refresh the entire braking system on its own, and its Toyota-specific fitment must match the vehicle’s year and Tacoma stud configuration. The product is described as a direct-fit replacement, not a larger-rotor or caliper conversion. I’d shortlist it for a compatible Toyota with front-brake needs; owners wanting a matched four-wheel overhaul should look at the K2813-36 instead.
Pros:- Front-only package suits repairs where the rear brakes do not need replacement.
- Includes two Z36 carbon-fiber ceramic pads, two drilled and slotted rotors, and installation hardware.
- Designed for listed Toyota truck and SUV applications used for towing and hauling.
- Includes a 36-month or 36,000-mile limited warranty.
Cons:- Covers only the front axle, unlike the four-wheel PowerStop K2813-36.
- Fitment is limited to specified Toyota models, years, and configurations.
- The supplied product data does not specify rotor dimensions or confirm an increase over factory rotor size.
Best for: Toyota 4Runner, FJ Cruiser, or Tacoma owners with verified fitment who need a towing-oriented front brake replacement while retaining serviceable rear brakes.
Not ideal for: Buyers needing front and rear components together, owners of unlisted vehicles, or shoppers seeking a larger-caliper big-brake conversion.
- Model number:PowerStop Z36 Truck & Tow K137-36
- Brake position:Front
- Compatible vehicles:2003–2009 Toyota 4Runner; 2007–2014 Toyota FJ Cruiser; 2005–2015 Toyota Tacoma (6-stud); 2016–2023 Toyota Tacoma
- Included components:2 Z36 carbon-fiber ceramic brake pads, 2 drilled and slotted rotors, installation hardware
- Pad material:Carbon-fiber ceramic
- Rotor finish:Silver Zinc Dichromate plating
- Item weight:41.8 pounds
- Warranty:36 months or 36,000 miles limited
Our verdict“Choose the K137-36 for a compatible Toyota that needs a front-axle towing-oriented brake refresh, not a complete four-wheel upgrade.”
PowerStop Z36 Truck & Tow Front and Rear Brake Pad and Rotor Kit K8171-36
I’d choose the K8171-36 when the goal is to replace pads and rotors at both ends with one truck-and-tow-focused kit. Its front-and-rear coverage sets it apart from the PowerStop Z36 Front K137-36, which covers only the front, and makes this a more complete option for buyers planning a four-wheel brake service. The listing identifies truck and towing use, but provides no rotor dimensions, vehicle fitment details, or specific performance figures, so I’d verify compatibility for the exact truck before ordering. The main tradeoff is that this kit may arrive in multiple boxes, which can complicate delivery and parts checks. I’d favor it over a rear-disc conversion kit when the truck already has compatible front and rear disc brakes and needs replacement components rather than a system conversion.
Pros:- Includes brake pads and rotors for both front and rear applications
- Identified for truck and towing use
- One kit can cover a planned four-wheel pad-and-rotor replacement
- Part number is provided for fitment research
Cons:- Vehicle make, model, year, and fitment details are not provided in the supplied product data
- May arrive in multiple boxes, complicating delivery and inventory checks
- Rotor dimensions and performance specifications are not listed
Best for: Truck and trailer owners replacing compatible front and rear pads and rotors together who want a kit identified for truck-and-tow applications.
Not ideal for: Owners who need only front or rear components, are converting from rear drums, or cannot confirm that part number K8171-36 fits their exact vehicle.
- Part number:K8171-36
- Fitment coverage:Front and rear
- Application:Truck and tow
- Included components:Brake pads and rotors
- Brake axle coverage:Front and rear
- Package note:May arrive in multiple boxes
Our verdict“Choose the K8171-36 if you need front-and-rear pads and rotors for a compatible truck used for towing, but verify exact fitment before ordering.”
How We Picked
I ranked these options by how clearly their stated application and coverage answer common truck-braking needs: fitment specificity, front-versus-rear coverage, suitability for truck and tow use, and whether the kit represents a focused upgrade or a broader brake refresh. I gave an advantage to packages that state their axle coverage and intended truck application, since a mismatched kit can mean wasted time and an incomplete repair.
The ranking also reflects meaningful differences rather than treating all six as interchangeable. The K2164-36 leads as a broad truck-and-tow front-and-rear choice; the other Z36 packages follow as alternatives whose exact fitment must be checked. The Detroit Axle kit earns a place for its defined HD-model range, the GM kit for a distinct classic rear-disc conversion need, and the front-only K137-36 for buyers who need a narrower repair. Product names alone do not establish rotor dimensions, hardware contents, or compatibility with every trim, so those details should be verified against the truck’s VIN and current configuration.

Factors to Consider When Choosing Big Brake Kit For Trucks
Before choosing a big brake kit for trucks, I’d separate the goal of the upgrade from the marketing label. A tow-focused pad-and-rotor package, a single-axle refresh, and a rear disc conversion solve different problems, and none should be selected without confirming fitment and the condition of the whole braking system.
Match the Kit to the Exact Truck and Axle
Start with model year, make, model, cab and trim details, drivetrain, axle, and existing brake configuration. Two trucks with the same badge can use different rotor sizes or brake hardware, especially across heavy-duty and light-duty versions. A kit that fits the model family may still exclude a particular production date or configuration. Check the manufacturer’s application list and compare it with the truck’s VIN or original equipment details before ordering. For older trucks, confirm whether the rear axle is the specified 10- or 12-bolt type and whether the wheel bolt pattern matches. Treat fitment confirmation as part of the purchase, not a detail to sort out after parts arrive.
Choose Front, Rear, or Complete-Axle Coverage
A front-only kit can make sense when the front components are due for service and the rear brakes remain in good condition. A front-and-rear package is a better match when both axles need work or when you want components selected as a coordinated set. A rear disc conversion changes the type of rear brake system, so it is not equivalent to replacing pads and rotors on an existing disc setup. Replacing only one axle can leave different friction materials and wear conditions across the truck. Before choosing, inspect both ends and check the service plan; buying coverage the truck does not need can add unnecessary work, while buying too little may lead to another repair soon after.
Set Expectations for Towing and Heavy Loads
Truck-and-tow branding signals an intended use, but it does not by itself establish stopping distance, heat capacity, or compatibility with every trailer load. Match the kit to how the truck is used: frequent towing, heavy payloads, steep descents, and stop-and-go driving place different demands on brakes. Also check the truck’s factory towing limits and follow safe loading practices; a brake kit does not raise those limits. If you tow regularly, look beyond the kit name and verify the specific pad and rotor design, included parts, and manufacturer application guidance. Drivers who mostly commute may value quiet operation and everyday usability more than a package aimed at heavier service.
Verify What the Kit Includes
Product titles can describe a kit broadly without spelling out every component in the box. Confirm whether it includes pads, rotors for both axles, caliper hardware, parking-brake parts, hoses, or conversion brackets as relevant to your application. This is especially important when comparing an existing disc-brake replacement with a rear disc conversion. Missing or reused hardware can affect installation time and may require separate parts. Ask a qualified installer or check the manufacturer’s parts list if the listing does not clearly state what is included. Do not assume that a matching product name means two kits have identical contents.
Factor in Installation and Brake-System Condition
A brake kit is only one part of a functioning system. Calipers, flexible hoses, fluid condition, wheel bearings, and the parking brake may also need attention, depending on age and wear. A rear disc conversion can involve more involved installation than a routine pad-and-rotor replacement, so assess labor, required tools, and any adjustments before choosing a do-it-yourself route. Follow the kit’s bedding procedure and the vehicle service manual after installation. If the truck pulls, vibrates, or has a soft pedal, diagnose the cause instead of assuming new rotors and pads will fix it. A professional inspection is a sensible choice when the system’s condition or fitment is uncertain.
Know When a More Extensive Kit Is Worth It
Paying for front-and-rear coverage makes sense when both axles need service or when a coordinated package matches the intended application. It is less useful if one axle is still in good shape and the kit’s extra parts would sit unused. A vehicle-specific HD package may be the better route for an owner whose truck falls squarely within its listed range, while a classic rear conversion is only relevant to the right older axle and configuration. Do not choose by the word “big” alone: rotor size and caliper compatibility must match the wheel, suspension, and factory system. Prioritize verified fit and a clear installation plan over an assumption that the most extensive package is always the strongest choice.
Frequently Asked Questions
How do I know which of these kits fits my truck?
Check the exact year, make, model, trim, drivetrain, axle, and brake configuration against the manufacturer’s fitment information. The listed applications already show why a broad match is not enough: the classic GM kit is for specified 1963–1970 C10/C15 6-lug trucks, while the Detroit Axle kit is listed for certain 2020–2024 Silverado and Sierra HD models. For the PowerStop kits, confirm the specific part number against your vehicle rather than assuming the Z36 name guarantees fit. Use the VIN or original equipment information when available, and ask the manufacturer or a brake specialist if the listing leaves any detail unclear.
Should I choose a front-only kit or a front-and-rear kit?
Choose based on which axle needs service and whether the other axle’s components are still in sound condition. The K137-36 is a front-only option, whereas the K2164-36, K2813-36, and K8171-36 are described as front-and-rear packages. A complete package can simplify planning when both ends are due, but it is not automatically necessary if the rear brakes have substantial service life remaining. Have the full system inspected before ordering, since worn calipers or other parts can change the scope of the job. Also check that the package contents match the work you intend to perform.
Is a truck-and-tow brake kit a good choice if I rarely tow?
It may still suit a truck used for hauling or demanding daily driving, but the label alone does not show whether it is the right match for your priorities. If towing is rare and your brakes simply need routine replacement, verify the kit’s intended application and characteristics before choosing a more specialized package. Consider how often you carry heavy loads, drive in hilly areas, or encounter repeated hard stops. The everyday tradeoffs you care about may include noise, dust, pedal feel, and maintenance, so consult the manufacturer’s product details. Do not expect a pad-and-rotor kit to change the truck’s rated towing capacity.
Does a rear disc conversion replace a standard pad-and-rotor kit?
No. The GM 10/12 Bolt kit is a rear disc conversion for specified classic C10/C15 applications, while the PowerStop packages are pad-and-rotor kits for compatible existing brake configurations. A conversion changes the rear brake setup and may involve additional brackets or hardware, so its installation and fitment checks differ from a routine replacement. Confirm the axle type, lug pattern, and all included conversion components before planning the job. If your truck already has rear discs, a conversion kit may not address the service you need. A shop familiar with the vehicle can help establish whether the current system is compatible.
Can I install a big brake kit myself, and what should I check first?
Some experienced home mechanics can handle a pad-and-rotor replacement with the correct tools and service information, but a conversion or unfamiliar fitment can require more skill. First confirm the kit is correct for the truck, identify every included and required part, and inspect calipers, hoses, fluid, and parking-brake components. Follow the vehicle manual and the kit’s installation and bedding instructions; brake work should not rely on guesswork. If the pedal feels abnormal, the truck pulls, or you are unsure about bleeding or hardware installation, have a qualified technician inspect the system. The cost of a fitment or installation error can outweigh the time saved doing the work without help.
Conclusion
For a broad truck-and-tow front-and-rear choice, I’d pick the PowerStop Z36 Extreme K2164-36 as the best overall option in this lineup, subject to exact fitment verification. The other front-and-rear Z36 kits, K2813-36 and K8171-36, are alternatives when their specific application matches your truck; compare their fitment and contents rather than treating them as interchangeable. For a focused front-axle job, the K137-36 is the most direct fit among these choices and may be the best value when rear service is not needed. Beginners should prioritize a clearly matched replacement kit and have a professional confirm fitment and installation needs, rather than starting with a conversion. For 2020–2024 Silverado or Sierra 2500/3500 HD owners, check the Detroit Axle application; for specified classic C10/C15 owners seeking rear discs, the GM conversion kit addresses that distinct need. My final recommendation is to choose by verified truck fit and required axle coverage first, then compare the package details.
