The Wilwood Narrow Superlite 4R rear disc kit for Chevy 12‑bolt applications with a 3.15" bearing spec combines forged construction with parking‑brake capability for tight rear axle installations. FNSL4R four‑piston calipers, two‑piece 13" or 14" rotors and BP‑10 compound pads create balanced braking to complement front systems. The internal shoe is neatly hidden for clean installation and strong static parking hold; optional finishes let builders tailor the look.
