Wilwood Narrow Superlite 4R Rear P-Brk Kit 12.88in Drilled Chevy 12 Bolt-Spec 3.15in Bearing

Forged Narrow Superlite 4R rear disc kits offer a complete Big Brake solution for popular muscle car rear axles that need a parking brake. These kits are built around FNSL4R four-piston calipers, two-piece rotors measuring 12.88 inches, and high-performance BP-10 compound pads. They are designed to provide optimized and balanced braking that complements front big brake upgrades on custom, show, and high-performance street machines.

The calipers are forged for strength and feature a narrow profile, making them a good fit for axles that might have clearance limitations. The neatly hidden internal shoe system provides a clean installation while offering superior static holding power for parking. This means you get both strong stopping power and a reliable parking brake function without a bulky external setup. Wilwood offers optional caliper finishes and rotor designs, allowing you to personalize the style and performance to match your specific build.

This specific kit is configured for Chevy 12-bolt rear axles with a 3.15-inch bearing and a 2.81-inch offset. It includes drilled rotors, which help to dissipate heat and remove brake dust and gas from the pad surface, contributing to more consistent braking performance, especially under heavy use. When installing this kit, refer to the manufacturer's instructions for proper setup and any specific hardware requirements.
