Installed! Took me two evenings because I'm slow... Very beefy! My only reference was my 100 series slider steps, which attached with u-bolts. These seem obscenely stronger than those. The amount of area of the frame mounts is massive.
Trying to figure out the weakest point, and it's probably the 4, grade 8 3/8" bolts on the front leg. Would still take a big hit to damage them, I'm guessing. Very impressed.
They come with light mounting tabs, to which I mounted up some LED rock lights, but haven't wired up yet. I'm toying with cutting up the OEM lights and reusing them. TBD on that.
Install was pretty straightforward. I'm guessing as with all slider installs the hardest part of it was pretty much guessing where to cut the rocker cover. Leaving them in the 100° sun made cutting with box cutters pretty easy.
The only thing I would comment on, and I don't know what the solution is, would be there vertical adjustment of the sliders. The front mount is primarily horizontal adjustment, with the bolt slots running horizontal. The rear plate has vertical bolt slots, but also has mounting surfaces on the outside of the frame, as well as the bottom of the frame. That section of frame has a large weld on the bottom that makes it difficult for the plate to mount flush. Is it kosher to grind that weld down? I know there's probably tons of variability in 10 year-old frame dimensions, straightness, and weld thickness. I have about an 1/8" slope that I can't get rid of, likely my frame. Don't think it's visible, only bugs me because I slapped a level on it.
Anyway, LOVE the slidersteps!
