2023-2026 Jeep Gladiator JT TriXPoly Rear Fender Liners

The 2023-2026 Jeep Gladiator JT Rear Fender Liners are the quieter, cooler alternative to aftermarket aluminum. Most Gladiator owners upgrading their liners go aluminum - and immediately notice the rattle on every trail, the heat buildup in the wheel well, and the hassle of modifying a metal liner to fit. TriXpoly eliminates all three without giving up any protection.

These bolt directly to factory mount points with no drilling required, making installation straightforward and reversible.

Why TriXpoly Over Aftermarket Aluminum?

• No Rattle: TriXpoly absorbs gravel, salt, and trail debris impact noise that aluminum liners transmit directly into the cab.
• No Heat: Stays cool in the wheel well - aluminum superheats and transfers that heat to surrounding components.
• No Drilling Required: Bolts directly to factory mounting locations for a clean, OEM-style install.
• Easy to Modify: Trim with a razor knife if needed - no angle grinder, no metal shop required.
• OEM Matte Black Finish: Integrates seamlessly with the Gladiator's factory aesthetics.
• Complete Kit: Includes both driver- and passenger-side rear fender liners, a full stainless mounting hardware kit, and a step-by-step install guide.

Fitment Note

Fits all 2020-2026 Jeep Gladiator JT trims. The rear wheelhouse design has remained consistent across all JT model years, so this kit is identical in fit to earlier JT rear sets - same bolt-on install, same perfect coverage.
