Product Description

The PowerStop BBK-JK-002R Z36 Truck & Tow Big Brake Conversion Kit is engineered for the 2007-2018 Jeep Wrangler JK/JKU platform, especially those vehicles with larger wheels, lifted suspensions, heavy bumpers, and towing or off-road responsibilities. With rotors that are roughly 20 % larger than stock (13.5" front / 14.25" rear), this kit dramatically upgrades braking leverage, heat management and stopping power under demanding conditions.

Featuring cross-drilled & slotted rotor faces and a corrosion-resistant zinc plating, the kit is built for durability in harsh environments. The included Z36 Carbon-Fiber Ceramic brake pads offer low dust, quiet performance and fade resistance. With red powder-coated calipers and heavy-duty brackets provided, the installation remains bolt-on - provided the vehicle has 17" + wheels or clearance for the larger rotors.

Ideal for Jeep owners who tow trailers, add oversized tires or heavy off-road gear, this Big Brake Kit gives a significant braking upgrade for both street and adventure driveability. Before installation, confirm wheel clearance (17" or larger wheels required) and inspect that caliper, bracket and rotor fitment match your suspension/wheel configuration. Fitment confirmed through 2018; 2019 and beyond coverage is unconfirmed at time of listing.
