Description
Belly-Pan Design
To help you make it to the end of the trail, we're offering our most comprehensive and largest skid plate system we've ever designed. This is a true "belly pan" system that protects all your vital drivetrain components. The new JL 8-speed transmission drives fantastic, but is very long and pushes your drivetrain further back underneath your rig. To protect your transmission and transfer case, we had to increase the size of our skid plates. This is where our "belly pan" design gets to work. From frame rail to frame rail and oil pan to exhaust resonator, our design is comprehensive and complete.
Dual Crossmembers
Jeep had a brilliant idea to make the JL frame rails out of a new harder material, but trail testing has exposed a major flaw: thinner walls but stronger material twists! Early in 2018's Easter Jeep Safari exposed major flexing and twisting in rigs coming back off their day's runs. To prevent this plus strengthen our larger skid plates, we include 2 new 1" by 2" thick steel crossmembers. These CNC machined crossmembers extend from driver to passenger side frame rails and not only give our skid plates the foundation they need to protect your drivetrain, but also take twist and flex out of your frame.
