The Wilwood Narrow Superlite 4R rear disc kit for Big Ford old‑style rear axle applications provides a forged narrow big‑brake upgrade with a built‑in parking brake. FNSL4R four‑piston calipers, two‑piece 13" or 14" rotors and BP‑10 compound pads deliver balanced braking while the internal shoe offers strong static parking hold. The kit's clean installation and optional finishes allow builders to balance style and function.
