TJ progression to the 4500 class

I haven't been on here very much before now, so my original suspension build wasn't posted here. A few years ago I built a midarm with a triangulated rear, and a 5-link front. Always meant to build a proper 3-link with a more robust axle mount, but was hoping I'd have a more robust axle soon.

I wasn't able to put what I wanted into the Jeep, so here I am, with a V8, D30, and polishing that thing up. Finally got around to installing the extra parts I've had for 3 years.

Got 6.5 inches of bump in the front. Ordered some 12 inch travel Blsteins to match the rears.

Mock up.


Full bump, the trackbar joint just tucks up between the diff and coil perch.




Upper link is a recycled 1.5 solid rod from a friend's old Rock Krawler 3-link (junk, BTW), butted them up to some Currie joints, sleeved with 1.75x0.120 HREW. Tucks up between the starter and a-pipe.


Also had to trim out the motor mount some.


Ride height.




Upper link


None of this would be possible without cardboard.


What do you think of this upper mount tab?

You appear to have been talking to Blaine... the axle mount looks exactly like mine.

Saw that RE piece on your thread, said "I can make that...", and $20 in scrap 3/8 and 20 minutes I had it cut and bent up. Probably overboard, but I'm no engineer so I tend to be on the safe side of things. I even reused some old LCA tabs I made and ran for a while.

Those bushings with no plate on one side look kinda scary.

I'm 100% sure that's for mock up.

Can I see a pic of your front end from head on? Curious on your steering.

Sure Robert. As soon as I'm done cycling and welding it in, I'll slap the steering on and snap a pic. It's just the Currie stuff though.

Im curious as to why you got rid of the cast bushing part of the pumpkin? or is this a different housing? One of these days I plan on converting my currie suspension into a midarm setup. Ill be watching to see how you like it.

I didn't want to run a 2 inch joint. I know Currie and RockKrawler both have 2 inch joints that will take a 1/2 inch bolt, having the 9/16 bolt and larger ball in the 2.5 joint made me feel better.

I;ve been running the midarm for 3-4 years now. It has the best performance and ease of bunding inside the TJ body/frame than any other suspension. Long arms are too long, and well, short arms are too short. Midarms are JUST right.

Made a tab to brace the back, too a bit of working, but cut out a funky looking piece that follows the contours of the two mounts.

Can't really see it...








Just painted up, now for the shocks and the limit straps I got today.

Got the 3-link buttoned up, and got my Superior shafts, limit straps, and 12in travel Bilstein 5125s front shocks today.

Working on getting up and downtravel set so I can mount the shocks. I'll have 5.5 inches of uptravel, 6.5 inches of down. I'm limited my the track bar. Shaved a rib off the Solid diff cover, and the 3rd link is about 1/8 inch from the a-pipe.

Not very elegant, but here's my straightforward solution for a touch more shock uptravel in the front.


Stjjames is coming over tomorrow to bang the rest of it out.

this looks really good so far.
how does the front drive shaft fit around the new upper mount on the frame?
