Do I need skid plates for off-roading?
If you drive on trails, gravel roads, or rough terrain, skid plates protect your oil pan, transmission, and transfer case from rock damage. Our shop at 2175 Sampson Ave #116, Corona is about 82 miles from Thermal — most customers are in and out the same day.
What's the difference between steel and aluminum armor?
Steel is heavier but stronger and cheaper. Aluminum is lighter but more expensive. For serious off-roading, we typically recommend steel.
Can you install rock sliders on any truck?
We install rock sliders on most trucks and Jeeps. Custom fabrication is available for vehicles without off-the-shelf options.
We serve these nearby locations for off-road armor & skid plates:
“Got a full Rough Country skid plate kit installed on my JK Wrangler. The transfer case and oil pan skids are beefy and everything mounted clean. Floyd made sure the ground clearance was within my spec for the trails I run.”
“Jake installed rock sliders and a belly skid on my 4Runner. I've since run two trail days and everything held up without a mark. These guys know what they're doing for serious off-road builds.”
“LINE-X of Corona installed ARB skid plates and rock sliders on my Tacoma. Solid quality and the install was clean. They drilled into the frame exactly as the instructions specified — nothing improvised.”
