rear coil spring parts need advice

Well my first post,

I have a 97 TJ sport, putting on 2.5 RC lift, I've got it torn down. When I took the springs out (rear) there was a black plastic/metal piece that looked like a spring isolator on the bottom. I trashed them. I got new ones for the top, can't seem to find the bottom ones online. I found ones that are .75 thick but not the OG ones. Are they called spring isolators?

One other thing is the stock jounce bumper, when I took the old ones out I tore them up. Anyone know a good place to get these? They are the same size as the fronts right? I bought spacers to lower the stock ones.

Thanks

Wrangler Forum ROCKS!

Thanks a lot, I guess what I was trying to figure out was if the front and rear were the same size. (jounce) I put daystar on the front, then an extension on the back with a stock jounce.

Then for some reason the bottom spring perch looks bigger to me, the hole. I've got the tops, I'll give it a whirl.

thanks

Update? I'm going thru the same process. PO had install lift spacers and original bump stops and isolators are thrashed. Ordered new rear bottom and front top isolators, does the front lower and rear upper require anything? I can't find a rear upper isolator anywhere and never removed anything from the front lower perch.

use the stock jounce in front with bumpstop extensions bolted to the axle side...IMHO

read this:
A lesson on jounce bumpers

and use this write-up to determine proper bumpstop extensions...
correct bumpstop length

Ok. Last question. The isolators are held on by the bump stops correct?
