Rear Brakes Built To Stay Cool On The Long Way Down

A RAM 3500 that tows or hauls for a living asks a lot of its brakes, and the rear axle takes its share of the work every time you slow a heavy load. PowerStop built the Z36 Truck and Tow Brake Upgrade Kit for trucks that work hard during the week and play hard on the weekend. The pads use a low dust ceramic formula reinforced with carbon fiber, which gives you severe duty stopping power without making the truck harder to live with every day. They are paired with drilled and slotted rotors that keep brake temperatures down by maximizing heat dissipation, which matters on a long mountain descent with a trailer behind you. The rotors are zinc plated as well, so they are protected against rust and corrosion instead of turning orange the first time they get wet. Stainless steel shims on the pads help move heat away and keep braking virtually noise free. Everything comes in one box, including premium stainless steel hardware, a new pin bushing kit where applicable, and hi temp brake lubricant, so the rear job does not stall for a missing part. If you tow a boat, haul for the jobsite, or run big tires, this kit gives the back of your truck the hardware to keep up.

Vented Floating Rotors Paired With Severe Duty Carbon Ceramic Pads

The PowerStop K8776-36 is a rear brake upgrade kit engineered for 2019-2025 RAM 3500 trucks. It pairs Z36 carbon fiber ceramic pads with drilled, slotted, and zinc plated rotors, and the pads include stainless steel shims for heat dissipation and quiet operation. The rear rotors are vented floating rotors measuring 14.4 inches (365.0mm) in diameter with a height of 5.3 inches (134mm). Nominal thickness is 1.5 inches (38.0mm) with a minimum thickness of 1.4 inches (36.4mm). They use 8 holes on a 6.1 inch (156.0mm) bolt circle with a 5.0 inch (128mm) hub hole, and the rotor construction is a floating rotor with a drum in hub and rotor assembly. The kit includes premium stainless steel hardware, a new pin bushing kit where applicable, and hi temp brake lubricant. PowerStop recommends the kit for towing, hauling, big tire upgrades, mountain driving, and off road use.
