Product Description

The PowerStop KC7131-36 Z36 Truck & Tow Rear Brake Kit is engineered specifically for the rear axle of the RAM 3500 SRW (2013-2018). Built for heavy duty use under towing, hauling or large-wheel upgrades, this kit replaces the factory rear brakes with high-performance carbon-fiber reinforced ceramic pads, drilled & slotted zinc-plated rotors and powder-coated calipers - giving better stopping power, improved rotor cooling and a stylish, durable upgrade.

Everything needed is included in one box for the rear axle: rotors, pads, calipers and hardware. The bolt-on nature makes installation more straightforward for experienced mechanics or truck owners. Ideal for those using their trucks for heavy loads, trailer towing or performance upgrades, the KC7131-36 kit maintains cleaner wheels (thanks to the low-dust pads) while delivering strong braking confidence. Verify that your vehicle is the correct model year, rear axle lug pattern (8-lug), drivetrain (RWD/4WD) and factory brake configuration before purchasing.

This kit is ideal for truck owners looking to elevate their rear braking system without replacing the front axle. Confirm compatibility of lug pattern, rotor size and brake package, especially if your vehicle has aftermarket or dealer-installed brake upgrades. 2025 model year coverage is unconfirmed at time of listing.
