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.

Specs

Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
