As some of you guys know, I installed new GM rear spring isolators when I rebuilt my suspension. They were noticably bigger than the old ones, but I put them in anyway, figured they'd squish down a bit. After all was said and done, it sat a bit high in the rear. I let it go for about 3 months and it still sat a bit too high for me. I changed them out with the old ones and it dropped the rear almost an inch. The pics show the measurements. With the new isolators, the wheelwell clearance was 3" or so. After the swap, only 2 1/4".

So I guess you guys doing rebuilds should keep the old rear isolators. The new ones MUST be for 4th gens, and are the only ones they make anymore. Also, the old ones have a metal core or something, they're stiff. The new ones are all rubber.

More pics to follow.

Now it sits like this:

 

Thanks for the 411, Ed. I guess maybe I'll just stick with what I got!

 

the *** end sat high with the hotchkis springs as well on my ROC. that was with the old original gm isolators. i ended up cutting the damn springs and now sits nicely. i still want to lower it just a bit to match the front though.

 

Thanks Ed. Great information.
