Replacement Stock Height IROC-Z Rear Springs

I have searched and searched looking for drop in rear springs that will restore the ride height to factory. The rears are shot, the back end has a noticeable sag, (even sagging on both sides).

The best replacement recommended on these forums that I gave found is Moog's that need to be cut.

I have a hard time believing that the only way to get a factory ride height back is to buy springs and cut them. Am I missing something?

As CHEEEEEEP as they are, and EEEEEEEEEEEEEEEEEZY to change out, try em.

Moog CC635 is about as close to stock as you can get.

The Moog's are pretty much stock height, I have a feeling people forget how much springs sag over the years...

Re: Replacement Stock Height IROC-Z Rear Springs

as far as I know. the MOOG springs are direct replacements for factory ride height. the reason people cut them.. is because the NEW MOOG springs will make the car sit higher initially until they "settle in" your car is certainly sitting lower now than it did the day it rolled off the line. the moog springs should/will put the ride height back to about where it should be the day it rolled off the line. that is the answer.

Re: Replacement Stock Height IROC-Z Rear Springs

When I changed my original springs out on my Formula I found the replacement AC/Delco springs to be 2in taller. I cut about an inch off because I knew they would settle some but I don't put many miles on the car so that's why I went with a "happy medium"
