YJ Spring conversion

Just picked up a set of YJ springs, shackles, spring plates, and u bolts for $80. Best deal I've found yet! Curious if anyone knows or has a set 2.5 in hangers and perches?

Any pointers / how to tips for doing this on an intermediate would be great!

Thanks

I bought Jim's yj hangers and they rock. Use the google search function at the top left of the page and you should be able to find him pretty easy. He's a forum member and makes them.

Don't forget to move the front shackle bracket forward about an inch (you'll have to remove a frame rivet), since the YJ fronts are longer.

You'll also have to correct the caster. Most either cut and reinstall the spring perches, or use shims.

Good luck,

Matt

If you buy an aftermarket shackle hanger, like the MORE ones I did you don't have to remove the rivet in the crossmember. They have a hole that fits over it. I don't know about the crabtree ones though.

Maybe I missed something but I don't understand why you would have to correct the castor by changing to YJ from CJ springs. I get it if the OP were lifting at the same time, but OEM to OEM all it is going to do is move the front axle forward by 1/2", but it doesn't change the pinion angle by any noticable measurement.

Help me understand please?
