The Wilwood Narrow Superlite 4R rear disc kit delivers a big-brake upgrade to rear axles that require a parking brake, tailored here for Chevy 12‑bolt setups with C‑clips. It pairs forged FNSL4R four‑piston calipers with high‑friction BP‑10 compound pads and a compact internal shoe parking system to preserve clean installation and strong static holding power while complementing front big brake upgrades.
