Wilwood 140-17883-D Forged XRD Rear Disc Brake Kit Lug-Drive 11.44" Rotor

The Wilwood 140-17883-D Forged XRD Lug-Drive Dynamic Rear Disc Brake Kit delivers advanced thermal management and performance for drag racing and high-speed applications that generate significant rear brake heat. This innovative kit features Wilwood's patented lug-drive rotor mounting system with Dynamic Stainless Super Alloy rotors designed specifically for vehicles that rely heavily on rear braking power.

Key Features:

• Lug-drive rotor mounting system eliminates traditional rotor bolts for simplified installation
• Large internal snap-ring retention allows rotors to expand and contract independently from hats during heat cycles
• Removes all thermally generated stress from rotor attachment points for flatter, truer-running rotors
• Spring-loaded replaceable stainless steel inserts protect aluminum hats from wear caused by brake torque loading
• Dynamic Stainless Super Alloy rotors provide superior heat resistance and longevity
• Forged construction delivers maximum strength-to-weight ratio
• 11.44" rotor diameter with 2.81" offset and 0.68" rotor width
• Designed for Lambert/Midwest rear axle applications

This kit is engineered for drag racing and other motorsport applications where high-speed braking generates extreme rear brake temperatures. The lug-drive system's ability to eliminate thermal stress prevents hat distortion and maintains consistent rotor performance across multiple heat cycles. Available in single and dual caliper configurations to match your specific braking requirements.
