Mine are custom made, but extremely simple. Just a piece of 2" x 4" DOM box tube. Then welded to two 1" x 1" DOM tubes that are welded to the chassis.
Had a shop make them for like, 150 bucks, out the door. Had them make up some gas tank skids too. Damn gas tank skids cost more than the actual sliders :rofl: . The skids bolted into the 1x1 tube.
Cheap, looks decent, very effective. Been running them for about 2 years now.
