When the factory hardtop is removed, the revealed surface is left exposed and can be easily scratched, or damaged. aFe POWER has a solution that is both ruggedly tough, and off-road inspired to help protect the surface and enhance the look of your vehicle. On-road or off-road, the unique tire tread design and aFe POWER logo, repels any condensation, splashes, or spills to drain to the outside of the vehicle and not to the inside. The unique textured surface helps with grip when accessing top mounted storage containers or scouting the trail ahead. The Terra Guard Tub Rail Covers are constructed of a durable rotomolded polymer material that is both scratch and UV resistant so it can survive anything the trail throws at it. XLPE (Cross-linked Polyethylene) is not a paintable material. Engineered using 3D laser scanning and CAD software, the Tub Rail Covers are designed for a perfect fit. Although all vehicles are not built the same, the oversized mounting holes allow for precise placement to align with your vehicles door jams before securely fastening into place for a perfect fit and finish. Terra Guard Tub Rail Covers should be installed when the factory hard top is removed. This quick installation will ensure the painted body tub rail surface is never exposed long enough to be damaged. Whether using the factory hardware or the optional Stainless Steel security screws, both can be stored into the same factory tray holder in the back of the Jeep, so they are never misplaced. An optional stainless-steel security hardware kit is available, P/N: 79-90001. Stainless-steel provides good strength and corrosion resistance in bad environments like high temperature, cold weather and high humidity areas. The low-profile design sits flush with the tread pattern of the Tub Rail Covers, and the tamper-proof design requires a special tool that is included in the kit.
