Wilwood 140-14130-D Billet Dynapro Lug-Drive Rear Disc Brake Kit

The Wilwood 140-14130-D is a Billet Dynapro Lug-Drive Disc Brake Kit featuring Dynamic Stainless Super Alloy rotors. This kit is especially well-suited for vehicles that place heavy demand on the rear braking system, including high-speed and heavyweight applications that generate above-average rear brake heat.

Lug-Drive Rotor Mounting System:

The innovative lug-drive rotor mounting system eliminates traditional rotor bolts entirely. Instead, a single large internal snap-ring retains the rotor within the hat for fast, simplified assembly and installation. This design allows the rotor to move independently of the hat as it expands and contracts through heat cycles, removing all thermally generated stress from the rotor attachment points — keeping rotors flatter and running truer.

Key Features:

• Lug-Drive design eliminates rotor bolts; single internal snap-ring retains rotor in hat
• Dynamic Stainless Super Alloy rotors for superior heat resistance and durability
• Billet aluminum hats protected from thermal distortion caused by rotor expansion and shrinkage
• Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the aluminum hat from wear under brake torque loading
• Two rotor diameter options: 11.44" (standard) and 11.25" (for clearance with bead lock rims)
• Available in Single and Dual caliper configurations

The Wilwood 140-14130-D delivers a high-performance, thermally efficient braking solution for race and performance street applications where rear brake performance and longevity are critical.
