Product Details
This is the Wilwood Narrow Superlite 4R front big brake kit, designed to significantly upgrade the stopping power for a range of Jeep vehicles, including models like the Cherokee, Comanche, and Wrangler from the late 80s and early 90s. If you're looking to improve your Jeep's braking performance, especially after adding larger tires, suspension modifications, or simply want more confidence on the road or trail, this kit is a solid choice. It replaces your stock front brakes with a much more robust system, featuring larger rotors and powerful four-piston calipers.
At the heart of this kit are the forged Narrow Superlite 4R calipers, known for their strength and compact design, allowing them to fit within a 12.19-inch rotor. The kit includes vented, drilled rotors that help dissipate heat effectively, which is crucial for preventing brake fade during heavy use. The calipers come in a striking red finish, adding a visual upgrade that complements performance enhancements. Wilwood engineers these kits to be application-specific, aiming for a straightforward installation process that works with your original master cylinder and ABS system, where applicable.
This kit is a comprehensive solution for Jeep owners seeking a substantial improvement in braking capacity. It includes everything needed to get the larger rotors and calipers mounted up, offering a noticeable difference in stopping distance and pedal feel. For those with 1990-2006 YJ or TJ models, this kit can also be fitted if you're willing to swap to the earlier 84-89 YJ spindle. It’s a well-built system that pairs well with other vehicle upgrades, ensuring your Jeep stops as well as it performs.
