looks like my buddies ran with you guys last week. how did the 80 do on 35sI just completed the rubicon this past weekend and these arms performed as advertised. I don’t know how much more up/down travel I had compared to those running plates but it as definitely noticeable. And boy did I abuse them on the trail. I haven’t really noticed any dents but I’ll take a closer look and will post pictures of all the damage occurred, can’t really say that bout my front bumper thoughView attachment 2706091
Did great. Least of all 80’s with body damage. Couldn’t do little sluice though. Had to run the bypass. Front stock bumper was holding by a thread.
3L arms... I'm ready.
Let's do this.
I'll even take the demo set, a couple scratches wont matter.

Looks like its time for an upgrade.

I guess there *are* advantages to having a 93 or 94 model with the ABS bracket after all...

Can't believe those wires didn't tear. Broke it on the Rubicon but able to get it welded up at Buck Island and it held for the rest of the trail.
Zip tie for added strength.

Wow!
My first time seeing one break. Very impressive.

I clearanced the top of both arms below the tie rod probably 8 years ago. Looking at the failure, there was several mm's of rusted metal below where I clearanced but above the clean metal, so it looks like there was a small crack there for a while. In those 8 years, the truck has been on the Rubicon 5-6 times, Dusy Ershim 3 times, and in Moab too so those arms had plenty of contact with rocks. The final hit was a pretty good drop off onto a rock where the arm took all the weight of the truck before the DS slider made contact. It definitely was a hard hit. Afterwards I heard the DS front tire rubbing where it wasn't supposed to so I stopped to take a look.
I did get to see the Delta arms in person on a few 80s on the trail and they look plenty strong so I don't think this will be an issue in the future.
So you're saying that you removed (ground off) part of the arms for tie rod clearance at the point where it broke?

Yep. Couple of mm's but enough to create a stress point that did fail over time.

8 years of wheeling? I'd take those odds.
Think paint would have helped? or smoothing/contouring the ground area?

Paint, no. Smoother contour, possibly yes.
I think the PSA here is if you even slightly clearanced your arms below the tie rod and wheel moderately hard, time to get the Delta arms or scab plate the OEM ones.
Not the first or last to shave a little, so say those are pretty rare.
Thanks for clarifying for me. I had seen that was a fix suggested by some years ago. I agree that the Delta arms would be a much better route to go, but that wasn't availble back when you needed the fix.
Looks to me like your arms are clearanced waaay more than what I'd consider "slightly"... Most 80 arms that are ground for tie-rod clearance are barely noticeable. Yours look to be notched to the point that the entire top of the "I" beam shape of the arm is gone.
Not discounting the Delta arms at all, but I'd say your stock arms are a pretty extreme example.

Those big caster plates likely helped the arms bind up laterally sooner than they would have otherwise. Could have contributed to the failure.
