Wilwood 140-12552-D DPL Dual Rear Dynamic Drag Brake Kit SA Drilled Big Ford New Style

The Wilwood 140-12552-D Billet Dynapro Lug-Drive (DPL) Dual Rear Dynamic Brake Kit is engineered for high-speed, high-heat drag racing applications. Featuring Wilwood's Stainless Super Alloy (SA) drilled rotors in a dual-caliper configuration, this kit is purpose-built for cars that place heavy demands on the rear brakes — including high-speed, heavyweight vehicles that generate above-average rear brake heat. Designed for Big Ford New Style axles with a 2.50" offset, this kit delivers race-proven stopping power with a rotor diameter of 11.44".

Lug-Drive Dynamic Rotor Mounting System:

The defining innovation of this kit is Wilwood's lug-drive rotor mounting system, which eliminates traditional rotor bolts entirely. A large single internal snap-ring retains the rotor within the hat, making installation fast and straightforward. This floating design allows the rotor to expand and contract independently of the hat through repeated heat cycles, eliminating thermally generated stress at the rotor attachment points. The result: rotors that stay flatter and run truer over the life of the brake system.

Key Features:

• Dual Dynapro forged billet, lug-mount four-piston calipers for maximum clamping force
• Stainless Super Alloy (SA) drilled rotors — 11.44" diameter with 2.50" hat offset
• Dynamic floating rotor mount — snap-ring retention eliminates rotor bolts and thermal distortion
• Spring-loaded, replaceable stainless steel lug-drive inserts protect the aluminum hat from wear caused by brake torque loading
• Billet aluminum hats resist distortion from rotor thermal expansion and contraction
• Available in single and dual caliper configurations
• Alternate 11.25" rotor diameter version available for bead-lock rim clearance

The Wilwood 140-12552-D DPL Dual Rear Dynamic Kit is the ideal upgrade for drag racing applications demanding consistent, heat-resistant rear brake performance with simplified serviceability.
