Body vs frame mount sliders

[jbehrn]

Another frame mounted option, Shrockworks.

Does not use the pinch, and does not use the body bolts. Purely frame mounted.

Do these rails stick out far enough to be used as a step?

I prefer the body mount sliders, particularly Rock Hard. There would be a lot of leverage on the frame with frame mounts--the frame is pretty far inboard, and is thin. It relies on its shape, a box, for strength, not material thickness.

Does the fact that these frames are high strength steel make a difference ? (and this is the reason it's thinner - same strength as other steel at lighter gauges)

I’m not sure I agree. I absolutely don’t like pure body mount. Those are useless. But frame and pinch mounted are just reinforcing a connection that already exists between the body and frame. As long as the frame connection is really solid, it would take a hell of a hit to move the body. The frame mounts will win against flex in the body mounts. By using a bunch, if not all of those pinch weld holes that are usually empty, you’re also reinforcing that entire seam with the steel that’s bolted to it with clamping force. Just my opinion.

Bottom of the body mount bolts flex with the body so mounting there and the pinch seam is acceptable... mounting pinch seam and actual frame will break something because the body moves more than you realize.

That’s fair, and a very good point. Thankfully that’s exactly how mine are mounted. Thanks though for correcting me.

Just picked up the Evo bomber rockers with rock skins. Have a moab trip planned for the end of May so I’ll post an update afterwards.

Honestly, unless you're dropping your truck on the rails on a very regular basis, that's the best way to mount them. Bolt-on sliders for the frame interfere with most skid systems and weld-on is a commitment that most don't need to do.

Couldn’t agree more, and I’m waiting for my full belly skid, which would definitely interfere. I hit my frame and factory skids WAY more than sliders under the door. WAY MORE. I’ve hit underneath hundreds of times. Less than 5 on the sliders. The ones under the bed corners, that’s different. .

The cab is mounted to the frame with rubber mounts that flex. If you mount sliders to frame and cab you are making that solid and something will eventually crack. IMO, a good cab mount that spreads the hit over the entire length will be good enough for what I will do.

Small step, not getting whole foot on.

When I mounted mine, I stripped one or two bolts. The frame is so thin that there isn’t much room for the threads to grab. I had to drill those out more and order bigger grade 8 bolts.
Really made me question the strength of the frame mount unless welded.?‍

I know people have concerns about mounting to body bolts and pinch seam a la Rock Hard, but I’ve never seen anybody post any damage from them. Seem like a very sturdy option.

I really like the gusseted frame mounts of Poison Spyder even though with added drilled mounts. Does not touch the body at all which I prefer for now. Any feedback on this?
