One area of my 80 that I’ve wanted to improve is rear quarter panel protection. The Kaymar bumper, while superb, does not have side quarter panel protection hoops, and I’ve definitely punished the truck with impacts in this area. One of our editors, Tim Lund (former head tech guy at ARB) now runs his own small fab company, Wild West Fab, so I called Tim to commission a solution.

They came up with a sweet solution for Kaymar bumper owners: rear hoops made of seamless DOM 1-1/2 inch diameter, 1/8th thick steel tubing with a support brace welded across the center that let the rear body lights remain visible. They are attached via six bolts forward and five aft. My hoops are the prototypes. I’m pretty stoked with them, and will be testing it on the Rubicon trail this next weekend when I do the Marlin run in our 80.

Wild West Fab will be selling these at $245 for a set of two with all Grade 8 hardware included. I got mine powdercoated standard black, they will have custom color powdercoating available. His site is www.wildwestfab.com.

more pics

More pics. You can see where I've trashed the rear quarters in the past! Just look at the Yukon sticker and the missing fender flare!

Roger that, will do.
 
You bastard! You found another way to spend my money! :D

Will be very interested in your comments on these after you run the Rubicon.
 
Curious question - are the holes for the bolts tapped or just drilled thru to use nuts on the back side? Certainly not hard to tap them as that's what's necessary to add the latch for the tire carrier.

Druck - we can tap 44 holes instead of just 22!

These holes were drilled.

Did you add anything to brace the side wings of the bumper which those tubes are bolted to. If I'm not mistaken, there are no side supports from the bumper wings to the frame. Seems to me that if you lay the new tube protection aginst something the bumper will flex in, just making it a damage multiplier.

Tim and i discussed a back plate (inside of bumper that the nuts would lay on top of when tightened.

The Rubicon run will tell how these prototype hoops perform. Tim specifically asked for feedback so he can make a better product if need be. Don't jump to any conclusions yet! I'll post pics upon return for all to see. Cheers,

You know what, i didn't even take that into consideration and your absolutely right. I'd like to see these get nailed a few times on the rubicon to show me they wont bend in the wings upon impact. 4wd Toy Mag, please bust your way through the Con like a pinball :)
 
Ha! Going for the high score then--or a tilt!:grinpimp:

Heya Bear,

There are two supports inside the rear corner section of bumper. One, a spar type, is nearer to the forward mounts. This spar reaches towards the center of the truck and braces there. This spar should help resist bending inward under outside pressure.

Aft, one reason Tim had to use five bolts is because there are steel supports in the rearmost quarter corners, which keeps a sixth from being (easily) utilized. These, too, theoretically should help resist crush presures.

I talked to Tim about the concern, and A: he says cantilever effect should help quite a bit and B; he wants to see it after the Rubicon as well!

Ok - so lock nut or lock washer and nut on the back - certainly easier than tapping 22 holes for threads. :D

Wonder which would ultimately be stronger tho.

The lock nut would be stronger, assuming the same thread pitch, unless the thickness of the bumper wing is greater than the height of the nut. ;)


Great idea on the part though if the bumper wing can take it. Might also work for those with older Slee rears?
