Power Stop’s Z36 big brake upgrade kit for 2007 - 2018 Jeep Wrangler JK models is the ultimate brake upgrade kit for Jeep JK Wrangler owners who require maximum stopping power and style without compromising reliability. If you've installed a lift kit and oversized tires on your Wrangler or even if you tow a trailer from time to time, you’ll have the confidence you need every time you hit the brakes. Each direct bolt-on big brake kit features massive 13.5" front rotors and 14.25" rear rotors that have been drilled, slotted and zinc-coated to improve performance and prevent corrosion. Those larger rotors are paired with Powerstop's red powder coated calipers with heavy-duty Caliper brackets as well as our noise and dust free Z36 Extreme Truck and Tow brake pads. The red powder coated calipers not only look great but provide an added level of corrosion prevention for years to come. The Z36 Extreme Truck and Tow pad that comes in the kit was formulated for maximum braking power using our carbon fiber ceramic friction compound for noise-free and dust-free braking in all conditions. High temp brake lube is included for proper assembly.
