Product Details

We build these skids out of 1/4" thick 5052 Aluminum because of its superior formability and strength -- compared to many other alloys. The design and shape of the skids largely determine how rigid they will stay over time. We've designed these belly skids to tuck bolt heads up and out of the way, where possible (as can be seen on the rear crossmember and fuel tank skids).

Removal of the factory fuel tank skid is required for install, netting you a 1/2" gain in ground clearance; in addition, you will lose the weight of the factory steel gas tank skid.

A removable access panel is featured below the fuel filter/water separator housing so maintenance doesn't require dropping the entire fuel tank skid plate.

We also designed these pieces to be easily modified for use with popular aftermarket suspension kits (such as the Rock Krawler and other similar Long Arm Suspension systems), larger axles, and multiple engine choices.

The skid system weighs approximately 117 lbs, however, you will be removing about 86 lbs of the factory skids and cross members, replaced by this setup -- for a total weight gain of just over 30 lbs. If you opt for UHMW the JLU 3.0 EcoDiesel UHMW kits weigh in at 29 lbs.
