Forged Narrow Superlite 4R Big Brake Front Brake Kit (Hat)

The unsurpassed braking capacity of the Forged Narrow Superlite 4R four-piston caliper serves as the base of this 12.19” big rotor kit for these popular 84-89 Jeep YJ model vehicles (including Cherokee, Comanche, Wrangler and Wagoneer). Kits also can be fitted to select 1990 to 2006 YJ & TJ vehicles if retrofitted to the earlier 84-89 YJ spindle. SL4 kits are engineered application specific for simplified installation and full compatibility with OE master cylinder output and ABS functions where used. Big brake kits provide increased brake capacity and complimentary style with wheel, tire, and suspension upgrades. Optional caliper finishes and rotor designs simplify personalizing the style and braking requirements of any application.
