Wilwood 140-11389-D Dynapro Rear Disc Brake Kit for Big Ford Applications

Upgrade the rear braking performance of your Big Ford application with the Wilwood 140-11389-D Dynapro Low-Profile Rear Disc Brake Kit. Designed for dependable street and performance use, this complete kit combines a compact four-piston aluminum caliper with a drilled and slotted iron rotor to provide strong stopping power, effective heat management, and consistent pedal response. The low-profile design supports installation in applications where clearance is limited while maintaining the performance advantages associated with Wilwood braking components.
The kit includes a black powder-coated Dynapro caliper, an 11-inch drilled and slotted iron rotor, and a parking-brake-compatible offset hat configuration. The aluminum caliper helps reduce unsprung weight, while the durable black powder-coat finish provides corrosion resistance and a clean appearance behind the wheel. The offset hat is engineered for proper rotor positioning and helps accommodate the rear parking brake arrangement required by compatible Big Ford setups.
Wilwood part number 140-11389-D is a practical choice for replacing or upgrading a factory rear brake system with modern disc brake technology. Its four-piston layout distributes clamping force across the rotor for smooth, controlled braking, and the drilled and slotted rotor design promotes pad cleaning and heat dissipation during repeated stops. Verify vehicle compatibility, axle configuration, wheel clearance, and required installation components before ordering to ensure proper fitment.
