Are these stock springs?

Rear is sagging compared to the front. Just put in new stock replacement shock and no help. Wondering if they were changed out a previous owner?

Do these look like stock springs?

Shocks won't help on height

I don't see a tag on the spring so you are just guessing at this point. Stock springs had a tag and both are usually different with the options chosen. There are 5 or 6 different springs for our cars. I just went through this last weekend at Richard Clark's place, he pulled out the factory specs and tag IDs . We then measured the installed height and put them on a fixture that he made , measured the pressure at installed height so we knew where to go from there. Then we went through a bunch of springs at his shop and found a set that raised the car by just over an inch with higher spring rates. I will check with Richard as to which springs we ended up with.

Neither springs have a tag so I would appreciate the info on what you used.

those aren't stock...those are a variable rate cargo coil spring

Bryan those might be hard to find. Nothing comes up at gmparts direct.

Same here... Car actually sits even on all 4 corners, 26 3/4...but I like a little rake....So I'm going to get some new MT 255/60's so there is an inch maybe? Then add some bags unless I go with a HR rear bar.

Can I use the same air bags that the stock springs use?

 

[pacecarta]

yes

Probably going to have to call Intercooled88s or James and have them look for a set on a car they have stripped .

I was lucky enough to be at Richard Clark's when the problem arose , he had a set and we installed them at the shop.
Cargo springs may be a good choice as an alternative.
