The unsurpassed braking capacity of the Forged Narrow Superlite 4R four-piston caliper serves as the basis of these 12.88” or 14.00” inch big rotor kits for the popular Ford Bronco vehicles. SL4R kits are engineered application specific to these vehicles, providing simplified installation. Each kit is engineered vehicle specific and utilizes the existing hub assembly. Big brake kits offer 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.
