Wilwood 140-14134-D Dynapro Lug Mount Rear Brake Kit Big Ford Drilled Rotors

The Wilwood Billet Dynapro Lug-Drive Dynamic Stainless Super Alloy Rotor Brake Kit delivers exceptional performance for vehicles that demand superior rear braking power and heat management. This rear disc brake kit is engineered specifically for high-speed applications and heavy vehicles that generate significant rear brake temperatures.

Innovative Lug-Drive Design:

The advanced lug-drive rotor mounting system eliminates traditional rotor bolts in favor of a large single internal snap-ring that retains the rotor in the hat. This breakthrough design allows the rotors to move independently of the hats as they expand and contract through heat cycles, effectively removing all thermally generated stress from the rotor attachment points. The result is rotors that stay flatter and run truer throughout their service life.

Key Features:

• Big Ford New Style application with 2.36-inch offset
• Drilled rotor design for improved heat dissipation and wet weather performance
• Stainless Super Alloy rotors for maximum durability and resistance to warping
• Spring-loaded, replaceable stainless steel inserts protect aluminum hats from wear during brake torque application
• Eliminates hat distortion caused by thermal expansion and shrinkage stresses
• Tool-free rotor installation and removal with snap-ring retention system
• Billet construction for precise tolerances and consistent performance

This Dynamic Rear Kit configuration is ideal for racing applications, street rods, and performance vehicles where rear brake efficiency and thermal management are critical to overall braking performance. The SA (Stainless Alloy) rotor material provides superior heat cycling characteristics compared to conventional iron rotors.
