Coil over on a yj

I am thinking about doing a coil over suspensio on a wrangler yj does anybody have any thoughts or suggestions on this matter. I plan on making alot of parts myself just having to buy the coils and shocks. Is there other things that i may need to be concerned about. The more informaton the better.

Coil overs....or just coils?



Coils would be easier unless you're going fullwidths.

FRONT:
XJ HPD30 with some RE 3.5" coils, Blue Torch Fab Coil buckets for the frame side. Custom trac-bar w/johnny joint and a poly bushing on the other end. RE XJ Super-Flex control arms (or a custom Y-link setup similar to TNT's XJ long-arm kit)

REAR:
Poly-Performance 4 link kit with some RE 5.5" springs and BTF coil buckets.



Its not going to be easy on stock width axles either way, and you'll probably have more into the suspension than the Jeep when all is said and done
(gotta factor in built axles and bigger tires too...)

Things you'll need to consider (if you're haven't done them already)
  • Extended Brake lines
  • Longer shocks and shock towers
  • SYE and CV driveshaft are going to be MUST HAVE items if you are going big enough to warrant coil-overs (or even a coil swap)

It will not be cheap to do a 4link suspension on a YJ. You better do all kinds of research on it before you start it. When you think you know wheat you are doing, research more. If you are going to 4 link your rig, you might as well upgrade the axles with you are there. D60 rear and D44 front minimum. don't half *** it!

Edit... also, that online 4 link calculator is pretty much worthless unless you are building a tube buggy from the ground up.

It will never work



BTW I have full width axles and without them this would be very hard to do as you just run out of room.

nailer341 is in the middle of doing a coilover on his YJ. I got a glimps of it last week. It's a work of art fitment-wise with an HPD30, but he's almost there & no doubt alot of fab work is involved.

Perhaps he'll post a few pics that'd help if you're looking at keeping the D30.

Coil suspension:


See the coild are what hold the rig up. the shocks just work as typical shocks..

This is a coilover suspension:


See the coil and the shock are one in the same and that is what hold your rig up. and a typical coilover cost about $500 each.

But you could also do a similar set up to the coilover and use Airshocks. they will runn $250-300 each depending on brand, size and who you buy them from.
This rig is running airshocks:



now do you want to get into a quarter elliptical suspension?

I guess my question is: Why do you want to do it?? Is there a reason that pushed you in this direction???

coil over

The reason that i want to do the coil spring suspension is because I put a 3.5" lift on and the ride is just so bouncy and rough that i can not stand it. I have taken it out in the woods but i think if i did a coil spring lift that it would be alot nicer ride and that s what i am going for. I want to be able to have a nice ride but also be able to take the jeep in the woods and feel safe as well.

coil over

Yeah i realize there are different options but it is not even enjoyable to drive on certain roads and the roads that i have to come to work are not enjoyable so therfor i am thinking of different ways that i can make it more enjoyable and the coil spring is the way that seems to me the best way to get that result
