Hey everyone, new to this forum (not to jeeping, not to lifting...but definitely new to long arm type suspensions)

I've been researching for the rear end on my 87 comanche. already have the front end designed (in my head) to do a 4 link.

it's sitting right around 7" right now. I'm keeping it at that height, or dropping an inch or two and sacraficing clearance for COG.


anyways, I have four 3" superflex joints, 4 currie d30 UCA flex joints (two with the disco reinforcement mounts). I have 4 stock UCA bushings and 4 stock LCA bushings, which I machined sleeves up for out of 3/16" wall tubing, matched to size accordingly.

I also have 8 poly bushings, 4 UCA and 4 LCA, with collars.

a couple of things I have basic questions about. would it be more ideal to use the stock (rubber) style bushings on the body end, or the poly bushings?

front will be a 4-link. it will not be a y-link and I'm not comfortable with the idea of a 3 link. I already have a belly skid and mounts designed.

the rear is a different story. I keep debating between some form of triangulated 3 link and a 4 link. again, y-link is out of the picture.

good things I've gathered about traingulated 3 link...
much more flex, great centering control so a lack of need for a pan hard/track bar

negative...
roll-steer
will need a beefy sway bar to avoid it rolling while driving

4-link is pretty straight forward to me. i comprehend it, and just need to get the geometry right. i don't like the idea of running a track bar if I don't have to.


my shocks are 11" travel edelbrock IAC extreme travel eternal reservoirs. I intend to end up with 3 or 4" up-travel, and 7 or 8" down-travel using those shocks. I'll design it with allowance for more and use appropriate limiting straps to keep it in the realm of what I can afford (the budget doesn't allow for another $1000 or more in shocks).

I'd like to know the opinions on this set up. and yes, i know there are other threads on this...and yes, i have looked and research. i'm just looking for your personal opinions on how you would do it on a comanche, and your preference between triangulated 3-link and traditional 4-link. no, a "traditional" 3-link or a y-link are not in any way going to be under consideration.

well i knew it was a tough crowd but....I guess I'll not expect any opinions from anyone then.

I would go triangulated 4 link myself. Drives nice and no track bar. Most of this stuff has been covered 8.62593 bajillion times, hence the lack of responses.

k thanks I will search that as well.
