      _x000D__x000D_

      Construction and Appearance. This kit incorporates forged Narrow Superlite 4R calipers made from durable materials and finished with a corrosion-resistant red powder coat. The rotors are vented iron with a black electro-coat finish, enhancing heat dissipation, corrosion resistance, and visual appeal. The drilled and slotted design helps reduce brake fade and improves pad bite.

      _x000D__x000D_

      Installation. Installation is moderately straightforward for professionals and experienced enthusiasts, as this kit replaces the factory rear axle flange without requiring drilling. Verification of fitment with axle offset (0.00) and flange configuration is recommended to ensure compatibility. A minimum wheel diameter of 18 inches is required.

      _x000D__x000D_

      Warranty. The kit includes a manufacturer’s warranty protecting against defects in materials and workmanship for a specified period.

      _x000D__x000D_

      Application. Specifically designed for 2018 through 2026 Jeep Wrangler JL models, this kit retains full utilization of the original equipment parking brake and brake system components to ensure seamless integration and reliable performance.
