Wilwood 140-14141-D Billet Dynapro Lug-Drive Rear Disc Brake Kit with Dynamic Stainless Super Alloy Rotors

The Wilwood 140-14141-D Billet Dynapro Lug-Drive Disc Brake Kit is an engineered high-performance braking solution designed for vehicles that place heavy demand on rear brakes. This kit is ideal for high-speed, heavyweight performance and racing applications where above-average rear brake heat is a concern.

Innovative Lug-Drive Rotor Mounting System:

Unlike traditional bolt-on rotor designs, Wilwood's lug-drive mounting system eliminates rotor bolts entirely. A large single internal snap-ring retains the rotor within the hat, simplifying both 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. The result is rotors that stay flatter and run truer under demanding conditions.

Aluminum Hat Protection:

Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the billet aluminum hat from wear caused by rotor loading under brake torque. The aluminum hat is no longer subjected to distortion from the stresses of thermal expansion and contraction, preserving long-term dimensional integrity.

Key Features:

• Dynamic Stainless Super Alloy Rotors — superior heat resistance and durability
• Lug-drive rotor mounting — snap-ring retention eliminates rotor bolts for fast, easy assembly
• Thermally independent rotor movement — rotors float freely in the hat to prevent thermal stress and distortion
• Replaceable stainless steel lug-drive inserts — protect billet aluminum hat from wear
• Available in two rotor diameters — 11.44" standard diameter and 11.25" for clearance with bead lock rims
• Available in Single and Dual caliper configurations
• Billet aluminum caliper and hat construction

The Wilwood 140-14141-D is part of Wilwood's Billet Dynapro Lug-Drive series, purpose-built for racers, performance street builds, and any application requiring consistent, fade-resistant rear braking performance through repeated high-temperature cycles.
