This Big Brake Conversion Kit is a front & rear axle for 2007-2018 Jeep Wrangler (JK/JKU) models. This bolt-on upgrade is recommended for Jeeps with suspension lifts, bigger tires and increased weight due to steel bumpers, skid plates and other heavy modifications. This kit features a set of new extended caliper brackets. The new brackets are used to relocate the caliper position to accommodate the new 20% larger rotors. The rotors are drilled & slotted to provide maximum cooling and silver Zinc plated to help protect against rust and corrosion. The Z36 Carbon-Fiber Ceramic brake pads provide a great pad bite and fade-free braking performance both on and off the trails. The Z36 pads also feature a premium stainless steel shim for better heat dissipation and virtually noise-free braking. Performance Brake Calipers are made specifically with the enthusiast in mind. These calipers bolt directly in place of the stock calipers, and they look and perform great behind stock or custom wheels. The Caliper and the Bracket are remanufactured in our Chicago, IL facility and treated to a high-temperature red powder-coating. This brake kit includes premium stainless steel hardware for an easy, problem-free install.
