The Wilwood Narrow Superlite 4R rear disc kit for Big Ford old‑style rear axle applications is a forged narrow big‑brake solution equipped with parking‑brake capability. It combines FNSL4R four‑piston calipers, two‑piece 13" or 14" rotors and BP‑10 compound pads to produce balanced braking that complements front big‑brake upgrades. A hidden internal shoe provides superior static parking hold, and optional finishes let builders customize the look.
