Overview:

The Kentrol Textured Black Door Hinge Liners are a premium upgrade designed specifically for the 2007–2018 Jeep Wrangler Unlimited JKU 4-door models. These liners address a common issue with the factory brass bushings, which are prone to premature failure, corrosion, and require frequent maintenance to stay quiet and functional. Crafted from high-quality black Delrin, these liners provide a durable, low-maintenance solution that enhances the longevity and reliability of your Jeep’s door hinges.

Ideal for Jeep enthusiasts who demand lasting performance and reduced upkeep, these door hinge liners improve hinge operation and help maintain the structural integrity of your doors over time. Whether you use your Wrangler for daily driving or off-road adventures, Kentrol’s liners deliver a dependable upgrade that keeps your doors operating smoothly.

Key Features:

Engineered to replace the factory brass bushings, these Kentrol door hinge liners offer several advantages:

• Made from premium black Delrin, a high-strength, low-wear polymer
• Self-lubricating properties reduce the need for regular maintenance and lubrication
• More durable and longer lasting than traditional brass bushings, especially in high-use conditions
• Resistant to corrosion, preventing the common issues associated with factory brass bushings
• Lightweight design contributes to overall vehicle efficiency
• Textured black finish complements the rugged aesthetic of the Jeep Wrangler
• Includes a specialized installation tool for a straightforward upgrade process
• Designed to work exclusively with original equipment (OE) door hinges for perfect fitment

Construction & Design:

The Kentrol door hinge liners are precision-molded from black Delrin, a durable acetal resin known for its excellent wear resistance and low friction characteristics. Delrin’s self-lubricating nature means these liners maintain smooth hinge movement without the need for frequent greasing, unlike the factory brass bushings that require ongoing lubrication to prevent noise and wear.

The liners’ textured finish not only enhances the visual appeal but also provides additional grip and stability within the hinge assembly. This thoughtful design ensures consistent performance and reduces the risk of hinge play or misalignment over time.

Installation & Fitment:

Installation is straightforward and designed for Jeep Wrangler Unlimited JKU 4-door models from 2007 through 2018. These liners are compatible only with original equipment (OE) door hinges and will not fit aftermarket hinge assemblies. The package includes a dedicated installation tool to simplify the process, allowing for a secure and precise fit without the need for specialized equipment.

Replacing the factory brass bushings with Kentrol’s Delrin liners helps eliminate common hinge noises and extends the service life of your door hinges, making this an excellent maintenance upgrade for Jeep owners.
