Construction & Design:

The Kentrol Door Hinge Liners are expertly crafted from high-grade Black Delrin, a thermoplastic known for its exceptional mechanical properties including low friction, high stiffness, and excellent dimensional stability. This material choice ensures the liners resist deformation and wear even under heavy use and exposure to dirt, moisture, and temperature fluctuations common in off-road environments.

The textured surface design improves the liner’s grip within the hinge assembly, reducing unwanted movement and noise. Each liner is precision-molded to match the exact dimensions of the OE bushings, ensuring seamless integration without the need for additional modifications or adjustments.

Installation is straightforward and user-friendly, designed to be completed with basic hand tools. The package includes all necessary hardware and a specialized installation tool to facilitate the removal of old bushings and the insertion of the new Kentrol liners. These liners are engineered exclusively for use with factory original door hinges and will not fit aftermarket hinge assemblies.

Fitment covers 2018 and newer Jeep Wrangler Unlimited JLU 4-door models and 2020 and newer Jeep Gladiator JT models, making them an ideal upgrade for owners looking to maintain or restore their Jeep’s door hinge integrity.
