I just want to preface this discussion by stating my understanding of the "tweaking" issue of the ARB bumpers has a lot more to do with the bumper mountings slipping on the frame horns than it is to do with the crush cans actually tweaking. That's what I've read elsewhere, if somebody has factual evidence of the crush cans actually bending, I'd love to see it.
The ARB is held on with 4 bolts through the factory frame horns. I believe the attachments at the ARB end are slotted to adjust the fit. The bolts are close set and in the same plane. This is a weak bolting arrangement.
I've seen photos of the DI ARB bumper, and it appears to have a 3rd set of bolts behind the front two, which help prevent the bar from twisting. The DII frame precludes this because it has some cross-members welded up immediately behind the front two holes.
I've finally seen a picture of an un-mounted RTE, and it's not *that* much different than the ARB. I expected to see some large reinforcing protrusion which bolts somewhere back on the frame to resist torsional loads but.. nothing.
I do see that each mount has an extra ear which wraps underneath each frame horn and there is an extra bolt which goes up through the frame. I imagine you have to drill a hole? Is that it? Just that single extra vertical bolt is what makes this bumper so much better?
Is that it or am I missing anything else?
