very nice!

renforcements good!

So is it going to be solid steel across the frame? And how are you attaching it to the frame rails?

You might also want to consider another cross brace in the larger area if possible.

I bent the sh*t out of mine this weekend so I'm curious to see how this works for you. The added clearance would have been nice, but that also means it's closer to the t-case, driveline, etc. if it does bend.

It looks like the H3's cross-member will serve as an additional brace in the large area. I'm not sure it will matter much if she's using 1/4" steel -- that will be very tough to bend. But then again, HI seems good at breaking things.

Nice job. Keep the pictures coming.

Your right on bjc.

As for mounting, there is an angle iron brace welded to the back subframe between the transfer case and the fuel tank which will have 4 holes drilled into it. In the front there is a L-shaped angle that was welded to the subframe underneath the engine (3rd pic). There will be 2 mounting holes drilled into the angle. Mounted w/ 3/8th grade 8 bolts. That's it in a nutshell.

I'm looking forward to attempting to break it.

Looks good HI. The only thing that could cause you some problems on the trail would be the bolt heads sticking out beyond the UCP. If those can be recessed, then you stand a better chance of them not catching and shearing off.

Hrmmm...good point. Hopefully they will be pretty flush and won't pose a problem. Thanks...

You can get panhead bolts in Grade 8, then use a tiny hole saw into the plate to countersink. The slopes on the side of the panheads should allow most rocks to slide over w/out ripping the head off, plus since they are allen heads, you won't have to worry too much about being able to get them out later. If you countersink them just up to the edge of the side lip on the bolt (like maybe 1/16"), I'd be surpised if you ever shear them off and I doubt it would affect the strength of the plate enough to matter.

Is the support bracing 1"x.0125"? It's hard to tell from the pictures. I'm curious as I'll eventually be building one of my own and want to steal all your ideas
