I'm installing a set of their bolt-on 5th gen sliders right now. The Easy side (passenger side) is complete, and let me just say: WOW!, so far this is a top-shelf, quality product with clean welds, stout steel, and laser-precise fitment that still allows for a little wiggle fore-and-aft to get all the hardware started.
And, lets talk about hardware, I think there is something like 24-25+ pieces of hardware on each side, with huge 3/4 lag bolts that go through the the front face, frame, and then through stiffening plates on the back side. Seems rock solid.
Also the ship time was very reasonable, the staff was very friendly and the price, for such a high quality part, is very fair, IMO.
I'm going to be installing the more involved drivers side, but, this being my like 12th 4x4, i'm not fazed, concerned or disconcerted by un-bolting, moving aside and re-bolted stock items. My last 4x4 had me welding up sliders, cage, and winch mount, so this seems like a vacation in comparison.
