Rubicon Express has everything you need to protect the vulnerable undercarriage of your 12-18 Jeep Wrangler JK with the 3.6L from front to back, with skid plates for your engine oil pan, transfer case, and fuel tank. All of the skidplates are CNC laser cut from 3/16-inch steel to withstand even the worst abuse, and are designed to mount up tight to the drivetrain to maximize ground clearance. The modular protection system allows you to add skidplates as your needs and budget allow without any concerns about compatibility.
