This is a place where you should consider material properties and statics, not internet hype. The hoops are perfectly fine. (.24in * 58,000lb)(2) = 27,840lb Combine both with a bridle (overkill) and it's 55,680lb breaking strength. Do you plan on exceeding 50,000lb of force on them? If not - use them for what Toyota engineered them for. If you do - I'm curious how you intend to do it.

Its pretty easy, took me about 30 minutes.
-Dropped the skid
-Unbolted sway bar
-Unbolted the small hose brackets that the top bolt uses
-Got the points roughly in position and attached loosely using the lower M12 bolts
-Reattached small hose brackets through the point
-Reinstall sway bar (hardest part, easiest to get one bolt started so its holding itself up then get the second one)
-Tighten everything down
-Install LFD wide skid instead of wimpy factory one. ;)

I was told that Toyota engineered them as tie down points and NOT recovery points.

You were told wrong.

Well, I trust my source. We can leave it at that. I'm not here to argue.
Either way though, its not an expensive mod in the grand scheme of mods, and adding reinforcement to something that can see high force levels during recovery can't hurt. I've spent way more money on way more useless mods in the past.

Hmm. Towing though. I'd say their definition of towing is probably a bit different than a kinetic recovery from thick mud, uphill, in the snow. With a vehicle that is 2,000 pounds over weight lol.
Either way, I like them.

2 x 12mm grade 8.8 bolts only have a shear strength of ~ 14,200lb combined. So if you had to choose between a bolt on point and the OEM one - the bolt on is only about half the strength. It's only as good as it's 2 or 3 bolts holding it in place. In a sideways pull the bolt on ones are probably less than 1/4 of the strength of the OEM hoop.

I think you're comparing two different things though. The weld on the hoop is the strength of the hoop, not the hoop itself. I've personally seen broken hoops. They don't break in the middle of the hoop, they break where the weld fails and the hoop separates from the frame. The hoop is still in one piece.

Jetboy, you gotta stop bringing science, engineering, and strengths of materials into this argument. It’s just not as sexy as red and shiny.

Can you please share the part number? The ARB web site is useless

Yea that site is a mess. I ordered mine from OK4WD, but I don't see them on there now.
Here's the write-up about them on trail4runner.com:
ARB Recovery Point Addition on a 5th Gen 4Runner, Instllation Instructions
They come individually, not in pairs. I think the part numbers are ARB-2821020 and ARB 2821030.

Not saying the factory tie downs are recovery or not but just offering my experience. Pulled a concreted in basketball hoop out of the ground with them that I had to rock and yank on a few times to get it to budge.
