      Description

      Front Big Brake Upgrade. The Wilwood Forged Narrow Superlite 4R Front Big Brake Kit with 12.19-Inch Drilled and Slotted Rotors and Red Calipers is engineered to significantly enhance the braking performance of factory disc-equipped Jeep Wrangler YJ models. It replaces the stock front brakes with high-performance components that provide superior stopping power, improved heat dissipation, and greater durability suitable for heavy-duty street or off-road use.

      _x000D_

      Construction and Appearance. This kit features forged aluminum calipers with a narrow four-piston configuration, ensuring lightweight strength and efficient brake force distribution. The 12.19-inch rotors are made from premium iron with a black electro-coat finish for corrosion resistance and include precision-drilled and slotted surfaces to optimize cooling and brake pad engagement. The alloy hats are anodized in black for a durable, stylish appearance.

      _x000D_

      Installation. Installation is straightforward for vehicles equipped with original factory disc spindles, requiring no drilling or modifications to the spindle or hub assembly. The radial mount calipers improve brake pad alignment and fit securely with included hardware, ensuring a precise installation.

      _x000D_

      Application. This brake kit is specifically compatible with the 1987 to 1989 Jeep Wrangler YJ models using the factory disc spindle configuration. It supports wheel upgrades requiring a minimum wheel diameter of 16 inches and allows braking capacity enhancements while maintaining compatibility with factory master cylinder and ABS components.
