Looking at possibly upgrading rear leaf springs on our 2008 34SS. Build code shows 15k rear springs but I noticed the PO upgraded the shocks and installed a rear trac bar. So I’m not sure if anything was upgraded as far as the springs.
I have some #s on the springs
Anyway to identify by looking?
I'm a new member on this site and just saw your post. Just in case your still looking for information, the Chevrolet dealer can tell by your VIN. I just replaced my rear springs and the OEM are no longer available.
