Do I need to replace rubber coil isolator w/ new springs?

Hey, I think I named the part right...its that rubber 'spacer' looking thing between the frame and the top of the coil.
Do I or should I replace that piece...?? Im putting in new ZJ coils this weekend! Later JTS

Reuse the old ones if they're still in good shape. TC

Not unless you see something unusual going on with yours.Its pretty new unless youve got extreme mileage/wear.

All I really have is a few minor indentations from the coils. Will these indentations affect the new coil position?

The rubber is too stoft to make a difference in spring alignment. I had a set of 3/4" daystar spacers that were not perfectly cut. Didn't make any difference. When lifting worry about your caster, track bar length and steering angles.

You're fine with the old ones. If they're shot it's pretty obvious thay they're falling apart. Minor indentations are ok, as long as you can't see the metal inside the isolator.

One of mine was destroyed, so they had to go, in this case get .75 spacers, they're the same thickness.
