Does Kirban still sell the stock front springs? I was thinking of either replacing my front springs or putting air bags or shocks up front to get it back up to stock ride height.

I just replaced my springs with MOOG replacements. You should be able to pick them up at your local parts house. Be sure that you get the GN T Type ones. They are specific to our cars.

They're actually the same springs all the G bodies got wit the F41 suspension option.

The stock fronts are Moog 5606's
The stock rears are Moog 6321's.

They should be about $45 a pair from your local autoparts store or Summit.

Are the Moog replacements stiffer than stock?

Thanks, Mike

Turbo6inKY is right on with the Moog part numbers. I just replaced my front springs with the Moog 5606 and really like them. A BIG tip: Torque the uper and lower control bolts with the car on the ground so that the weight is on the springs. If you don't your car will sit 3 inched higher in the front.

Thanks for the tip, But do they feel stiffer than the stockers

No, they're exactly the same. The numbers I quoted are the EXACT springs GM put in the cars on the assembly line.

Ok Cool, Do you know if Moog makes a replacement that is a little stiffer? And if so, Would you happen to know the part number?
I have new KYB's waiting to go into the car and I wanted to do this all in one shot

Thanks Alot, Mike
