Wilwood Narrow Superlite 4R Front Kit 12.19in 87-89 Jeep YJ

Starting with the forged narrow Superlite 4R four-piston caliper, this big brake kit is built for significant improvements in stopping capacity. It features 12.19-inch vented rotors that are 1.10 inches thick, designed specifically for a range of Jeep models including the Cherokee, Comanche, and Wrangler from the late 80s and early 90s. This kit is engineered for a straightforward installation and maintains compatibility with your OE master cylinder output and ABS functions, where applicable.

This Wilwood kit is a popular choice when upgrading wheels, tires, and suspension, as it complements those modifications with a substantial increase in braking performance. The robust construction of the Superlite 4R caliper, combined with the larger rotor surface area, means more consistent and powerful braking, especially under demanding conditions. You can also personalize the look with optional caliper finishes and rotor designs to match your Jeep's style.

If you're looking to enhance your Jeep's braking capabilities beyond the factory setup, this kit offers a well-built solution. It's designed to work with the original master cylinder and ABS, simplifying the integration process. For those with 1990-2006 YJ and TJ models, this kit can also be fitted if the earlier 84-89 YJ spindle is retrofitted, offering a path to improved braking for a wider range of Jeeps.
