cj to yj spring conversion + shackle reversal = ?

Okay so ive been trying to do some research and cant find much on doing a yj spring conversion and shackle reversal at the same time.. I have a soa on my cj7 with stock springs and i was wanting to convert to the yj springs. I know if i was doing a regular spring conversion id have to re locate my hangers but instead of relocating the fronts couldnt i just do a shackle reversal? anyone have this combined set-up?
Any help is greatly appreciated!
Thanks,
Alex.

From what I read, SOA and a shackle reversal don't mix well.

Ohhh okay. Well thank you. Are you using a kit or what when you do your yj spring swap?

The YJ springs are a little over an inch longer than stock front CJ springs.

I think you will need to either move the hangers, or buy different hangers that compensate for the longer springs.

I know opinions vary widely on the reverse shackle. My research turned up too many negatives, so I ruled it out.

Matt is on the right track. The front shackle hangers are too narrow to use, but rear CJ shackle hangers can be used for the front. They need moved one hole forward, where the crossmember rivit is. The rivit will need to be removed. On my new frame I set it up to be able to mount the hangers where needed as I wasn't sure what springs I would end up with.

Or, as I said earlier, you can buy 2.5" wide hangers and shackles, that will move the pivot point forward and allow you to use the same mounting holes.

Crabtree Tool and Die is a sponsor of this forum. Jim makes a beautiful set of hangers and shackles for the YJ conversion. I only used Jim's shackles, because I already had my hangers in place.

How much does the set usually run?

I didn't think he was making the hangers any more?? Just the shackles.

No doubt they are top quality hangers. If you can still get them.

skizriz,

Jim reconsidered his decision to discontinue the hangers when half the forum threw a fit.

So he bumped his pricing a little, and is still making them.

Well worth the premium price, IMO.

I've never seen them in person, but they sure do look sweet from the pictures I have seen.
Glad to hear he reconsidered.
