The Wilwood Narrow Superlite 4R rear disc kit for Big Ford new-style rear axle applications is a forged narrow big‑brake upgrade that includes a parking‑brake mechanism. It couples FNSL4R four‑piston calipers with two‑piece 13" or 14" rotors and BP‑10 pads for balanced braking to complement front systems. The neatly hidden internal shoe ensures reliable static parking hold, and available caliper finishes and rotor designs aid customization.
