The Wilwood Forged Narrow Superlite 4R front big-rotor kit for Ford Bronco applications pairs a four-piston SL4R caliper with a large 14.00-inch drilled rotor for improved braking capacity. Engineered to use the existing hub assembly and simplify installation, the kit suits 1966–1975 Broncos with Dana 30/44 front axles and includes options for caliper finishes and rotor designs to match upgraded wheels and suspension.
