Key Features & Benefits

• DigitalFit Laser-Scanned Precision — Computer-designed and built from laser-scanned measurements for a precise, OE-grade fit that follows every contour of your JL's cargo area with zero gaps or bunching.
• Proprietary Custom-Blended TPE Construction — Made from a specially formulated thermoplastic elastomer (TPE) that is wear-resistant and remains fully flexible under extreme temperature conditions — from desert heat to winter cold.
• Raised Perimeter Lip — A high outer lip traps spills, dirt, mud, and grease, fully containing messes before they can reach your factory carpet or floor.
• Skid-Resistant Textured Surface — The unique textured finish grips cargo to prevent shifting during transport, keeping groceries, gear, and equipment secure on and off-road.
• Easy Hose-Off Cleanup — Non-porous TPE surface wipes clean in seconds — just remove, rinse with a hose, and reinstall. No scrubbing required.
• FMVSS302 Flame Resistance Certified — Meets Federal Motor Vehicle Safety Standard 302 for flame resistance, ensuring your liner meets federal interior safety requirements.
• Proudly Made in the USA — Designed, engineered, and manufactured with American-made tooling in the United States by WeatherTech, a leader in vehicle protection accessories.

Frequently Asked Questions

Is this cargo liner CARB compliant or emissions-relevant?

This is an interior protection accessory with no impact on vehicle emissions. No CARB compliance is required or applicable.

It will fit, but note that the liner will limit the range of motion of the Trail Rail system if installed simultaneously.
