Upgrade rear braking performance with the Wilwood 140-17874-D XRD Dual SA Brake Kit, engineered for Big Ford applications. This complete rear brake system features dual four-piston calipers paired with drilled and scalloped rotors to provide strong stopping power, consistent braking response, and efficient heat management for demanding street, track, and performance use.
The system includes aluminum calipers finished in gray anodizing for corrosion resistance and a clean, durable appearance. Its 2.50-inch offset configuration is designed to support proper rotor and caliper positioning on compatible Big Ford rear axle assemblies.
