Product Details
If you're looking to significantly upgrade the braking performance on your 1965-1977 Ford Bronco, especially if you're running a Big Ford rear axle with a 2.36-inch offset and a 5 x 5.50 bolt pattern, this Wilwood Narrow Superlite 4R rear disc brake kit is a serious consideration. This kit replaces your stock 11-inch drum brakes, offering a substantial improvement in stopping power and a clean, integrated parking brake solution.
Wilwood has engineered this kit to provide a balanced braking system, complementing front big brake upgrades. It features their FNSL4R four-piston calipers in a striking red finish, paired with 12.88-inch two-piece rotors. The calipers are designed to be narrow, allowing them to fit within the 2.36-inch offset required for the Big Ford axle. What sets this kit apart is the high-efficiency drum-style parking brake assembly, which uses an internal shoe system. This design not only offers superior static holding power when parked but also maintains a clean look by hiding the mechanism.
This kit is a well-built solution for Bronco owners who demand more from their braking system. The combination of the FNSL4R calipers, performance pads, and the integrated parking brake makes it a comprehensive upgrade. While this kit is designed as a direct fit for the specified axle configuration, it's always a good idea to confirm your axle's flange type and bearing setup to ensure a smooth installation. You'll want to ensure your front brakes are also up to the task to take full advantage of this rear brake upgrade.
