Wilwood 140-17881-D Forged XRD Rear Disc Brake Kit Lug-Drive Dynamic 11.44" Rotor

The Wilwood 140-17881-D Forged XRD Lug-Drive Dynamic rear disc brake kit features innovative stainless steel super alloy rotors designed for high-performance applications where rear brake heat management is critical. This kit is especially beneficial for drag racing and other high-speed vehicles that generate significant rear brake temperatures.

Key Features:

• Lug-Drive Rotor Mounting System: Eliminates traditional rotor bolts, using a large internal snap-ring to retain the rotor in the hat for simplified installation
• Independent Thermal Expansion: Rotors move independently of the hats during heat cycles, eliminating thermally-generated stress at attachment points
• 11.44" Rotor Diameter: Traditional diameter provides excellent stopping power and heat dissipation
• Spring-Loaded Stainless Inserts: Replaceable inserts in each lug-drive slot protect the aluminum hat from wear caused by brake torque loading
• Forged Construction: High-strength forged components ensure durability under extreme braking conditions
• Improved Rotor Performance: Rotors stay flatter and run truer by eliminating bolt-induced stress and hat distortion

This drag racing rear brake kit is engineered for vehicles that depend heavily on rear braking performance and need superior heat management. The lug-drive design represents a significant advancement in rotor mounting technology, providing both performance and maintenance benefits.
