Moog makes a good replacement set although I don't have them, lots of guys do. The numbers have been posted in here before.

How many miles on them? I might be interested if they are low miles and not all messed up.


See the thing is my springs seem to be kinda worn, they dont hold the car like I think they should. I plan on adding some bilsteins as well, but I wanna put some stock springs on there. Now these Moog springs? Are these the standard rs/z28 springs or actual IROC springs. I know it says IROC style, but that term gets thrown around alot. IROCs sit .5" lower than the regular Z28, so I dont wanna turn around and make my iroc sit higher than it should, just stock....

You shouldn't use used springs because they are over ten years old. They have lost their stiffness over the years and lots of weight loaded on them. It does depend on number of miles they have seen but even with zero miles they are as stiff as new any more

Ive actualy used moog springs before in my 85 TA and they were cheap and worked well...I dont have any parts stores that will order them anymore ,so thanks for the link that will work out good!

parts stores near me dont even keep "cheap" shocks in stock for the Camaro

all I can say is parts stores near me are "SLACK"

the numbers i posted are for the IROC/later model z28. they are about 700lbs front and 110 rear but the rears actually seem much stiffer than 110 lbs. i had my doubts but they work great! only 105 bucks with tax.

How do these compare to stock '92 GTA WS6 springs?

I also need to replace original springs and might decide to stick with stock height.

5662/5665 are the correct numbers. I have two boxes with them in the garage right now. Best price I found was through Summit...even with the shipping (or "handling") charges thrown in.

Summit sells Moog suspension parts. 5662 & 5665 are Moog part numbers.

I was just wondering how the extra spring rate affected the handling.
