Done that with the WH. Dropped around 4ft down rock face onto another boulder, contacted directly on the leading edge of the LHS slider. Guard and door bent up at bottom, pulled pinchweld across. We are modifying the angle bracket with some extra steel to tie it to the subframe to strengthen it up. They work fine, but not enough for what i do. The Sliders that CRDSTU sells down here have a tube outer similar to the SA ones as well. Mine are getting the outer tube treatment and we are also making some brush guards and tieing those to the Saguaro front bar to protect the guards.
I know with my 4xguard slider i can use my hilift on any of the spots and it gets within 1/2" of the door.

PS ive had to move to a 60" hilift now, with the notches on the Saguaro rear bar the 48" wouldn't get it off the ground!
