Wilwood 140-17880-D XRD Rear Disc Brake Kit Olds/Pontiac 2.81" Offset

The Wilwood 140-17880-D is a high-performance rear disc brake kit featuring Forged XRD Lug-Drive Dynamic technology with stainless steel rotors. Engineered specifically for Oldsmobile and Pontiac applications with 2.81" offset and 0.68" rotor mounting configuration, this kit excels in demanding applications where rear brake performance and heat management are critical.

Revolutionary Lug-Drive Rotor System:

• Eliminates traditional rotor bolts in favor of a large internal snap-ring retention system for simplified assembly
• Allows rotors to expand and contract independently from the hats during heat cycles
• Removes thermal stress from rotor attachment points, keeping rotors flatter and truer
• Spring-loaded replaceable stainless steel inserts protect aluminum hats from wear during brake torque application
• Prevents hat distortion caused by thermal expansion and contraction

Performance Features:

• Forged XRD construction with stainless super alloy rotors for superior strength and heat dissipation
• Designed for high-speed, heavy-weight vehicles that generate above-average rear brake heat
• Ideal for drag racing and other applications relying heavily on rear brakes for stopping power
• Precision-engineered for Oldsmobile and Pontiac rear axle configurations

This complete brake kit provides a significant upgrade over stock rear brakes, delivering consistent performance and improved durability in demanding motorsports and high-performance street applications.
