Product Details
This Wilwood Narrow Superlite 4R rear brake kit gives you everything you need to upgrade the braking performance on the rear of your vehicle, specifically designed for Big Ford Old Style axles with a 2.36-inch offset. Inside this kit, you'll find a pair of forged Narrow Superlite 4R four-piston calipers, two-piece 12.88-inch diameter rotors that are drilled and polished, and a set of high-performance BP-10 compound brake pads. This combination is built to provide a significant improvement in rear braking balance, especially when complementing a front big brake setup on custom builds, show cars, and high-performance street machines.
The FNSL4R calipers are forged for strength and feature a narrow profile, making them a great fit for applications where wheel clearance can be tight. The rotors are drilled to help dissipate heat and reduce weight, while the polished finish adds a clean look. A key feature of this kit is the integrated parking brake system. It uses a neatly hidden internal shoe system that offers superior static holding power, ensuring your vehicle stays put when parked, all while maintaining a clean appearance behind the wheel. Wilwood offers optional caliper finishes and rotor designs, allowing you to personalize the style and performance to match your specific build.
When installing this kit, remember that it's designed to work with Big Ford Old Style rear axles. The 2.36-inch offset is specific to certain axle configurations. It's always a good idea to consult the manufacturer's installation instructions for detailed guidance on proper setup and any specific hardware or adjustments needed for your application to ensure optimal performance and safety.
