Wilwood 140-18160 Forged Narrow Superlite 4R Rear Big Brake Kit for 1971-1991 GM Full-Size SUVs

Upgrade the rear braking performance of your 1971-1991 GM full-size SUV with the Wilwood 140-18160 Forged Narrow Superlite 4R Big Brake Kit. Designed for disc/drum rear applications, this complete system combines a high-strength four-piston caliper with a precision-machined slotted iron rotor to deliver improved braking control, consistent pedal feel, and dependable performance for street, performance, and custom vehicle builds.
The Forged Narrow Superlite 4R caliper is manufactured from lightweight aluminum and finished with a durable black powder coat for corrosion resistance and a clean, professional appearance. Its rigid forged construction helps provide even pad loading and reliable clamping force, while the narrow profile is engineered to support installation in applications with limited wheel and suspension clearance. The included rotor features a slotted surface that helps maintain clean pad contact and supports consistent friction during repeated braking.
This Wilwood rear brake kit is specifically configured for compatible GM full-size SUVs from 1971 through 1991, including applications such as the Chevrolet Blazer. The integrated component design helps simplify a rear brake upgrade while providing the quality and engineering expected from Wilwood performance brake systems. Verify vehicle application, axle configuration, wheel clearance, and related installation requirements before ordering to ensure proper fitment.
