The Wilwood 140-18154-DR is a complete front big brake upgrade kit engineered for 1971–1991 Blazer applications. Built around the Forged Narrow Superlite 6R (FNSL6R) six-piston caliper in a striking red SRP finish, this kit delivers substantially increased stopping power over factory brake systems while adding a bold, high-performance look behind your wheels.

At the heart of this kit is a 12.19-inch diameter rotor paired with a 6-lug bolt pattern configuration, making it a direct-fit solution for compatible full-size truck and SUV applications. The FNSL6R caliper features a forged narrow-body design that provides excellent rigidity and heat dissipation while clearing a wide range of aftermarket and factory wheel sizes.
