So you're saying widen the rear links where they mount to the housing? I read somewhere 30* was a general rule as minimum, but I could be mistaken. Can remember what my value is off the top of my head, but I wanna say upper 30's

Widen the rear lowers at the axle housing "as much as possible"

Ditto the uppers at the chassis. EDIT... looks like your UCA brackets at the axle housing are pretty final, and aligned with the current angle of the UCAs.

If you can spread the lowers at the axle, you'll probably be pretty well set.

Yes, get them as wide on the axle as you can for the lowers. It takes 45* of convergence to keep the axle located laterally with only compression/tension on the links. That's in a perfect world. It won't be the end of the world if you miss by a couple degrees but, being in the 30's, the links will also have a bending moment on them, rather than just compression and tension. You really want to avoid that if at all possible.

I would put the frame side of the uppers on those angled tubes outside your frame rails and call it good.

I'm really curious to see how you'll be mounting the tub to it. I also think you should stretch that chassis out to CJ6 length and send me the plans.

I really do appreciate all the suggestions. may have shot myself in the foot on the uppers since I already burned in the up mounts on the hsg. I'll definitely be widening the lower links and doing my best to achieve the 45*. I was trying to save most on the floor as possible, but looks like thats gonna be more work than its worth to just say there's factory metal left in it Planning to make a flange off the "sliders" that the tube will bolt to along with various other points of mounting. Rear rails I was gonna bend up similar to the front,but after doing some thinking a two piece with mounting plate to the step in the floor is kinda the direction I'm heading. I'll try and post some updates, but dealing with fixing the front housing right now...

Hard to tell in the pics but the ram was just tacked to a piece of 2x4 to get an idea for heights. Started working on the actual mount/skid today.

Really not a fan of the over the top ram "rollcages" that I've seen on rig while surfing the web, so decided to go as low pro as possible and take the chance for damage.

Had an oddball size on tube laying around (1-3/8"x 3/16" wall) Opted to use this to keep it looking light but still take a little abuse.

Been pretty busy with work/life lately so progress has been pretty slowly. I plated in the front of the truss and began wrapping that up for the most part Still needing to add various gussets here and there, but you more or less get the idea on how its gonna look.

Is that the T-case you plan on running pictured above?

Edit: never mind I re read the first page. Looking great!

I really like how the ram mount came out. Clean and beefy.

How much caster did you build into the front housing when you installed the C's?

I was honestly clueless when it came to set up caster, especially since I've never driven a rig with full hydro. Talking with a lot of friends and getting their opinions on it, they kept bringing up KOH rigs and saying alot of those guys throw an ungodly amount of caster in hopes to get some feedback in the wheel. I know the farther you go it begins to strain steering components and what not, but I settled on 10*. Not having the the 3rds and drivelines to set pinion, I'm figuring to lose maybe a few degrees and still have no less than 7* at ride height.

More or less finished up the ram mount FINALLY! Just need to weld it to the housing. Didn't want to throw a ton of heat at the front end so had it tacked in only 3 spots that were easily accessible with a cut-off wheel. Pretty happy with the outcome, but there's always a few spots you wish you could go back and get a second chance at

[IMG]IMG_20180310_124106751 by Alex Velasquez, on Flickr[/IMG]

I try my best to avoid starting and stopping, but we all know thats not always possibly, especially when warping is number one concern.

[IMG]IMG_20180310_132645694 by Alex Velasquez, on Flickr[/IMG]

Should've welded the horizontal first and overlapped with gusset... Kinda stuck doing it this way so it didn't pull up a bunch.

[IMG]IMG_20180310_132723154 by Alex Velasquez, on Flickr[/IMG]

Wanted to place the outside gusset on the main plate, but caught myself before tacking it up there. I still need to fully weld the mounting blocks and with the gusset that close I wouldn't have been able to weld inside and out the gusset. Had to compromise and move it out farther, but still adds some strength. (Plane to add one on pass side as well, but will go on during final welding)

I can't wait to see where this ends up. Are you going to try to keep the CJ5 body lines more than a buggy look?

Plan is to keep as much of the factory tub as possible. Obviously there will be trimming needed in the rear to clear tires and will nee to modify grill slightly to account for rail height changes, but for the most part if will be a factory tub squeezed on "buggy" chassis. Also, being a on the younger side, I'm sorta thinking ahead so planning to build with the intent of a rear seat for the future.

Yaaay someone is building stuff on pirate again and the pictures work!

Looks great. I was thinking of selling my rig but threads like this make me want to tear it all apart start making stuff again.
