Fits 1975-1987 Chevrolet C10/R10 and GMC C1500/R1500 pickups, Suburbans, and Jimmy models equipped with Wilwood Modular Drop Pro Spindles.

The Wilwood Forged Narrow Superlite 6R (FNSL6R) front big brake kit is engineered specifically for square-body GM trucks to deliver professional-grade stopping power. This system centers on the high-strength, six-piston FNSL6R caliper, providing increased clamping force and thermal stability for show trucks, high-performance street builds, and track applications. The 14.00-inch rotors significantly increase braking leverage and heat dissipation over factory components.

This kit is designed for a simplified installation, maintaining full compatibility with original equipment master cylinder output and ABS functions where applicable. Please note that this specific configuration requires the use of Wilwood Modular Drop Pro Spindles for proper fitment and geometry.
