that's not a whole lot of protection. I mean, i'm not knocking it, it looks great, but why not take the bar up a little higher?
Looks awesome! I hope it holds up. What thickness of plating did you use? It looks to give significant strength to the Kaymar wings and has, IMHO, much better looks than the Wild West mod. - Kudos - good job!
Edit: What's the rear view look like? Just to see how far away from body the hoop is. Thanks!

In defense of Lenross1 - the higher you make the bar, the more leverage a hit will have on the wing of the Kaymar. IIRC, Dave Zartman (4WDTO Editor) mentioned after his Rubicon run, just after installing the Wild West hoop, that the hoop did not have to be as tall as it was. I got the feeling he was implying that ample protection could be achieved with a shorter hoop. And it makes sense to me, unless you prefer an Exo - type protection. IMHO

i did not. i will probably be redoing the sides anyway to get more clearance, so i wanted to see how this does first
too much leverage and after talking to several 80 owners that had smaller hoops or plate they said it was ample protection. we'll see.
yes thanks. if you look at what i was proposing in the beginning of thread, what i ended up with is about half the size. seems to be stronger also-less leverage.
I understand in theory. But when you are on the trail and you spend the time and money to add protection to the rear quarter panel, just seems like it would protect a little more then the 5 or 6 inches that bar is. Maybe it's a little taller then that, but you catch my drift.
I remember the thread Dave put up, and IIRC the hoop never flexed into the body and it did protect his quarter panel several times.
In my neck of the woods, we wheel a lot of muddy and slick trails with roots, rocks and wash-outs. I find myself sliding into the side of a rut or root all the time.
just constructive criticism. Time will tell the story and i hope i am wrong.

i used 3/16 inch angle iron. here is a pic of the rear. this side started to pull out a little farther when i started to weld it
. i need to tack the top as well as both sides. now i know

Nice to see good options out there for Kaymar protection! The Wild West hoops absolutely do hold up to savage abuse. I just returned from yet another trip to the Rubicon with them on my 80 for Marlin's run. I have put full weight on them...they literally saved me from tipping on that "wave" rock just before the Springs. Truck tipped over right side and the Wild West hoops caught the truck as it went. They had the full weight of the truck on them! Loved that.
The rear lower wing center support ribs as shown in other photos have proven themselves to be more than sufficient. As wheelers we all know they could be thicker/better. That said, they support the wings under pressure...see above.
I actually had them (the WWOR hoops) designed and built for me, originally, to save the rear quarters from trees here on the tight Washington trails. A tree branch had torn out my PS tail light and dented the body there. You can see the dented metal in the Yukon Gear sticker in the pic. Thus, they are taller, enough to actually protect the body up higher. They just also happen to do killer in rocky terrain as well.
Also on Kaymar strength--for any Rubicon run the back of my 80 has: two driveshafts, front and rear axles (4 total), two birfs, three tool/spare parts boxes, ARB 45-quart fridge full of food and drink, compressor, spare fluids/oil bucket, then camping gear and equipment for three occupants. Sometimes a scuba tank and gear for playing in the pool at the Springs. It's HEAVY. Here's a pic of it after it crashed down on the Kaymar, on the slabs just above Buck Island. You can see that 100% of the weight at the rear is supported solely on the bumper--the 35" tires are off the ground!
The Kaymar is an Aussie bumper, built for Aussie terrain not the Rubicon, which is why it's so great that it holds up to rock bashing like this, for which it was never designed.
R.e.: the hoops. Tim can make them shorter, taller, wider...custom is his business. Looks are subjective, true, but strength is not...I stand by them 100%, triple Rubicon tested, nuff said!
since you first published info on these hoops. 
Reread that entire thread and can't find where I thought he said that
- not sure where I got the idea.https://forum.ih8mud.com/80-series-tech/177968-trail-update-kaymar-bumper-hoops-wild-west.html
I'm with you there and in agreement. It just floors me that Dave is able to get the protection he does with those WW bars. I mean, it's obvious the Kaymar's not designed to do what he's putting his 80 through, yet it appears to give adequate protection.
Truely remarkable, Dave! I'm convinced and looking forward to "upgrading" my Kaymar.Nice to see good options out there for Kaymar protection!

thats alot of weight on that Kaymar!
Way to test it out Dave!
my eventual plan is to curve in the corners similar to the 4x4 labs bumper, basically put the Kaymar on a diet! We'll see how she does.
Thanks for the feedback guys its been really helpful!

Be sure to keep us updated on how your testing comes out. I think that with the amount of input and the number of Kaymar owners, we all will benefit when someone like you, steps up to the plate and gives his ideas a try. My hat is off to you, good luck!
Is this what you're looking for? LCwizard has it.
What bumper is that ^ ???

Isn't that the one that is offered by Man-a-fre that you have to have your truck at the shop to be fitted and installed?
I wanted to make sure the OP is not thinking i'm bashing his idea!! I hope this works out. Just was adding my 2cent of constructive criticism.

well the quarter panel protection did well, but apparently i need to protect the body from the kaymar bumper ?!
i came down off a rock too hard and it sent my bumper into the quarter panel popping off the rear quarter panel plastic.
I am used to a better departure angle then my fat assed 80
the bumper is closer to the body now.

The HannaQuality ones seem very strong but kind of goofy looking.
Need a couple more pics in better light at different angles. My '94 doesn't have that plastic trim, but it seems like you'd need some serious bumper-body contact to deform body enough to pop your panel off. Hard to tell from your pic, but is bumper still contacting body? My DS wing support flexed in to body enough to dent it, but currently has space away from body. I think there's 2 kinds of forces on the wings: side and bottom. Your added bar helps in the side force protection, but does little when it's attacked from the bottom. Just too much overhang with Kaymar to avoid that kind of force. Kaymar needs either serious trim job or beef up job to help there.well the quarter panel protection did well, but apparently i need to protect the body from the kaymar bumper ?!
