Wilwood 140-17875-D XRD SA Rear Brake Kit with 4-Piston Calipers for Big Ford

Upgrade your Big Ford rear braking system with the Wilwood 140-17875-D XRD SA rear brake kit. Designed for performance-focused applications, this complete kit combines lightweight aluminum four-piston calipers with drilled and scalloped rotors to deliver responsive braking, effective heat management, and consistent pedal feel. The gray anodized calipers provide a durable finish while complementing a range of high-performance builds.
The included rotors feature an 11.25-inch diameter and a 2.36-inch offset for fitment within compatible Big Ford rear-end configurations. Drilled and scalloped rotor surfaces help promote cooling and reduce rotating mass, making this Wilwood XRD SA system a practical choice for drag racing, street performance, and other demanding applications where dependable rear braking is essential.
Designed as a matched rear brake solution, the Wilwood 140-17875-D kit helps simplify installation compared with sourcing individual components separately. Verify axle, wheel, bracket, clearance, and hydraulic compatibility before installation to ensure proper fitment. Professional installation and appropriate brake-system setup are recommended for safe operation and optimal performance.
