Description

The Wilwood 140-14066-R Forged Narrow Superlite 4R Rear Big Brake Kit is designed to enhance the braking performance of Jeep Wrangler (JK generation) vehicles from 2007-2018. It combines four-piston calipers with BP-10 compound pads and 13”-14” rotors. This kit is specifically engineered for high-performance street and show applications, while retaining full functionality of the original equipment (OE) parking brake, master cylinder output, and anti-lock braking system (ABS). It also offers a complementary style and performance upgrade when paired with 13-inch or larger front brake kits.
