Wilwood XRD Lug-Drive Rear Disc Brake Kit Big Ford Offset

The Wilwood XRD Lug-Drive Rear Disc Brake Kit is a bolt-on rear disc brake conversion for Big Ford style axle housing flanges. It was developed for drag racing and other high-performance builds. These rear drag brake kits use Wilwood's forged XRD calipers and stainless super alloy scalloped and drilled rotors. They are built for cars that rely heavily on the rear brakes, and for fast, heavy cars that generate above-average rear brake heat.

Key Features:

• Lug-drive dynamic rotor mounting: A single internal snap-ring holds the rotor in the hat, so no rotor bolts are needed. This also makes assembly and installation easier.
• Independent heat cycling: The rotor can expand and contract separately from the hat. This helps the rotor stay flatter and run truer, and it keeps heat stress from distorting the hat.
• Super alloy rotors: The stainless rotors are lightweight, scalloped and drilled. They are sized for clearance with 15-inch rear beadlock wheels.
• Forged XRD calipers: The calipers are made for drag race use and come in single and dual caliper configurations, depending on the kit.
• Race-ready hardware: Kits include brake pads, rotor wear clips and mounting hardware as documented by Wilwood for each kit.
• Big Ford axle flange compatibility: The kits are matched to Big Ford axle housing flange styles, with offset options available as separate part numbers.

Wilwood designs its bolt-on rear brake conversion kits for strong braking performance and a clean, detailed look. Choose the variant that matches your axle flange and offset.
