Wilwood 140-7140 Dynalite Rear Brake Kit with 4-Piston Calipers for Big Ford

Upgrade the rear braking performance of your Big Ford application with the Wilwood 140-7140 Dynalite brake kit. This complete system combines lightweight aluminum four-piston calipers with a 12-inch plain iron rotor to provide consistent stopping power, improved pedal response, and dependable performance for street, performance, and competition-oriented vehicles. The calipers feature a durable black powder-coated finish for corrosion resistance and a clean, professional appearance.
The kit includes a Big Ford-specific mounting configuration, one-piece vented rotors, offset hats, and parking brake provisions for added installation flexibility. The 2.50-inch offset design helps accommodate rear-end and suspension layouts that require additional rotor clearance, while the vented rotor construction promotes heat management during repeated braking. The Dynalite caliper design offers an effective balance of rigidity, weight savings, and serviceability.
Designed for enthusiasts and builders seeking a complete rear brake solution, the Wilwood 140-7140 kit is engineered to work with compatible Big Ford applications and should be matched with the vehicle’s front brake system, wheel clearance, and master cylinder specifications. Verify application requirements before installation to ensure proper fitment and balanced braking performance. This kit is not air restricted and does not require truck freight shipping.
