Skid Plate System for Jeep JL 4-Door 3.6L 2021-2022

Builders pushing the newer Jeep JLU platforms in rocks quickly find the factory underbody still leaves critical drivetrain components exposed. The transmission, transfer case, fuel tank, and exhaust all sit in areas that take abuse on difficult trails, and factory protection often creates edges and drop points that can hang up on obstacles. With the engine mount changes on the 2021-2022 3.6L platform, underbody packaging changed as well, which is why this skid system was developed specifically for these model years. The Motobilt MB1099-42 Skid Plate System was designed to solve that with a true flush belly approach built specifically for the 2021-2022 Jeep JLU 3.6L. This 4 piece skid system uses keyed overlapping panels and recessed hardware to create a smooth underside with no exposed bolt heads or lips to catch on rocks. The boat side design improves how the Jeep transitions across obstacles while the integrated crossmember adds strength and rigidity to the chassis layout. Designed from a builder’s perspective, this is more than armor. It is part of the underbody structure. Heavy 3/16 inch steel construction protects critical components while maintaining serviceability with a dedicated oil pan access panel and removable skid sections. Notched ends allow a vehicle lift to still be used for repairs, something often overlooked in skid system design. For builders running the updated JLU platform, this system delivers underbody protection, smooth belly clearance, and serviceability for serious trail use and rock crawling.

A flush belly system removes exposed edges, bolt heads, and drop points that can hang up on rocks. It creates a smoother underside that slides over obstacles more effectively. Does this Jeep JLU skid plate system improve rock crawling clearance? It improves how the Jeep moves across obstacles by reducing snag points and using a boat side design, which helps with obstacle transition. Can I service my Jeep without removing the full skid system? Yes. The system includes an oil pan access panel and individual skids can be removed separately for maintenance and repairs. Will my rocker guards fit with this skid plate? Yes. This skid system works with all body mounted rocker guards and with Motobilt frame mounted rocker guards as well. Will this work with a long arm kit? Yes. Most long arm kits will not require modifications at the rear. Up front, most applications only require trimming the front edge of the skid plate to clear the front lower control arms. Product Components Instructions Installation Instructions
