PowerStop K7131-36 Z36 Rear Brake Kit 2013-2018 Ram 3500 SRW 8-Lug

Vehicle Fitment

• 2013-2018 Ram 3500 (6.4L Hemi V8, 6.7L Cummins Diesel I6, 4WD & 2WD) - Single Rear Wheel (SRW) models only; all trims

Fitment Notes

• Rear axle kit only - Single Rear Wheel (SRW) models ONLY; does NOT fit Dual Rear Wheel (DRW) models - those use different rear rotors and require a separate kit
• Z36 Truck & Tow compound is the recommended choice for Ram 3500 SRW owners who regularly tow or haul heavy loads - the Z36 handles sustained heat buildup under load significantly better than the Z23
• For a daily-driver Z23 version of this same rear kit, see K7131
• 8-lug bolt pattern (8x165.1mm / 8x6.5 in.)
• No special modifications required - direct bolt-on installation

Features

• Z36 Truck & Tow Carbon-Fiber Ceramic pad compound engineered for towing, hauling, and heavy-duty use - generates substantially greater brake torque than standard ceramic pads and resists fade under sustained load
• Purpose-built for the Ram 3500's heavy-duty towing and hauling demands - handles the elevated brake temperatures of long descents and loaded stops without fade
• Drilled & slotted vented rear rotors maximize heat dissipation and clear gas and debris from the friction surface under extreme operating conditions
• Premium stainless-steel pad shims resist elevated temperatures common in heavy-duty applications
• Low-dust formula validated through on-vehicle third-party testing - 30% less dust on average versus OE
• Silver zinc dichromate plated rotors resist rust and corrosion
• G3000 grade iron castings built to strict OE tolerances for crack resistance and durability
• Includes premium stainless-steel installation hardware and high-temp ceramic brake lubricant
• Bolt-on upgrade - no modifications needed

Product Description

The PowerStop K7131-36 Z36 Truck & Tow Rear Brake Kit is the heavy-duty rear brake upgrade for the 2013-2018 Ram 3500 Single Rear Wheel (SRW). The Z36 Truck & Tow Carbon-Fiber Ceramic pads deliver substantially more brake torque than stock and are engineered to handle the sustained heat loads of towing and loaded descents without fade - exactly what the Ram 3500's Cummins diesel and Hemi towing capability demands at the rear axle. G3000 iron rotors are precision-cast to OE tolerances for a direct bolt-on fit with no modifications required.

This kit is for SRW models only - DRW Ram 3500 models require a separate kit. For a Z23 Evolution Sport version of this rear kit better suited to daily driving without regular heavy towing, see K7131. For the matching rear kit with red powder-coated calipers, see KC7131-36.
