Rockhard 4x4 RH-90509 Skid Plate System for Jeep Wrangler JL The Jeep Wrangler JL is a fantastic evolution of the beloved JK, but it's not without its pitfallsespecially when it comes to undercarriage protection. While the JL offers improved suspension and fender flare clearance, it lacks essential skid plates to safeguard your drivetrain on rugged trails. This is where the Rockhard 4x4 RH-90509 belly pan skid plate system steps in, designed specifically for 2018-2021 Jeep Wrangler JL 4-Door models with the 3.6L engine (non-eTorque).
Belly-Pan Design Rockhard 4x4 has engineered one of the most comprehensive skid plate systems on the market. This true belly pan design extends from frame rail to frame rail, ensuring that all your vital componentslike the transmission and transfer caseare well protected. The JL's new 8-speed transmission is a great performer, but its length pushes the drivetrain back, making it more susceptible to damage. Rockhards skid plates are larger to accommodate this, providing peace of mind as you conquer tough trails.
Dual Crossmembers for Added Strength While Jeep's decision to use a stronger material for the JL's frame rails was innovative, it also introduced some flex and twisting issues during trail runs. Rockhard addresses this with dual 1" x 2" thick steel crossmembers that run from driver to passenger side. These CNC-machined crossmembers not only fortify the skid plates but also minimize frame flex, ensuring your Jeep stays stable and secure on uneven terrain.
Key Features Whats Included in the Kit Fitment Important Notes Customer Feedback Owners of the 2020 Jeep Wrangler JL have noted that the RH-90509 skid plate system provides excellent coverage without adding unnecessary weight. One user stated, "After installing the Rockhard skid plates, I tackled some serious rock crawling without worrying about my undercarriage. The peace of mind is worth every penny!"
