Wilwood 140-15302-D Front Disc Brake Kit for GM SUV and Truck, 6-Piston Superlite 4R Caliper

Upgrade the front braking performance of your classic GM SUV or truck with the Wilwood 140-15302-D Front Disc Brake Kit. Designed for applications using a C10 Pro Spindle, this complete kit combines a forged Narrow Superlite 4R six-piston caliper with a drilled and slotted iron rotor for responsive stopping power, improved heat management, and consistent pedal feel. The components are engineered for demanding street and performance use while maintaining a clean, purpose-built appearance.
The Forged Narrow Superlite 4R caliper features a rigid aluminum construction that helps reduce unsprung weight and supports precise pad engagement. Its black powder-coated finish provides durable corrosion resistance and complements a wide range of classic truck builds. The included 12.190-inch drilled and slotted iron rotor promotes efficient heat dissipation and helps keep the braking surface clean during repeated stops. This front disc brake kit is configured for GM SUV and truck applications from 1963 through 1987, subject to spindle, wheel, and vehicle fitment requirements.
Wilwood designs each component for reliable performance, straightforward service, and compatibility with high-performance braking systems. The 140-15302-D kit is a practical choice for replacing aging factory front brakes or improving the stopping capability of a restored or modified classic GM vehicle. Verify the required wheel clearance, spindle configuration, and related fitment details before installation to ensure proper clearance and operation. Professional installation and appropriate brake system setup are recommended.
