I have a 1972 LS5 with 67,000 actual miles on it. The rear shocks are air shocks with the line going from the shocks to the rear license plate bezel, where the fitting is located to air them up. I have never tried to air them up. My question is, are these factory equipment shocks, are or they aftermarket shocks? Was the 1972 corvette ever equipped with air shocks?
Thanks, Jimmie

Jimmie,

I doubt very highly that air shocks were a factory option. What you have described sounds like the very same aftermarket job I have done on a couple of pickup trucks I've owned. Why do it on a Vette? Maybe a previous owner didn't want to tackle replacing a flat rear spring and this was a simple and inexpensive work around. Letting all the air out will let you see if indeed your rear spring needs replacing. You can easily pump them up again with a mini-compressor that plugs into the cigarette lighter or even a bicycle pump.

Air shocks were never an option on your car. Like the other guy said,probably just a coverup for a weak spring. Easy way to find out is to release the air from the shocks and see how far the car squats down. Good luck and get rid of the air shocks. John

Thanks all for the information. I didnt think they were original equipment, but you never know until you ask. I will let you know if the car squats after letting the air out of the shocks. Jimmie
