Have my springs been heated and shortened? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi all,

My rear springs have an odd look to them - the coil spacing is closer in the middle, and the certifier has questioned whether or not they've been heated and shortened..

Can anybody tell me if this looks stock standard? or if they indeed have been heated and shortened..

The truck is still appears to be normal height.

Thanks!

hard to say, looks more like sacked out (Worn out) stockers.

Those look like stock springs. As long as they are not touching in the middle they are alright from what I understand. There was just a thread on that here recently.

Those springs are stock. I believe they are called progressive rate springs.

Thank you for your replies everyone! after quite a lot of googling I managed to find this which confirmed exactly what I was hoping.. they came from the factory like that

Not exactly, as I stated they are sacked, truck probably lost 3 to 4 inches of standard ride height. Probably matches the front. Think of it as a low buck lowering job.

Springs lose height from age and use, not a big deal, unless you are restoring to regain the stock stance.
