Is this a stock spring?
Just wondering if this is a stock spring, heavy duty, or what? Seems like most spring I've seen don't look "progressive" like this does. Any thoughts?

Re: Is this a stock spring?
Random ass guess, but perhaps someone heated it for a cheap "lowering" job. It looks sort of collapsed like that. A progressive spring will do that, but not that much without a load (if the spring is right for the application).

Usually with a progressive spring the top and bottom coils will be open and the coils will be closer together in the center.... Are both sides identical? LockDoc

Re: Is this a stock spring?
Both sides are the same and if anything the truck seems to ride a little higher than stock. I had about 1500 pounds of coal in the back and I measured about 6 inches from axle to bump stop. I was just curious. I've been contemplating lowering so I've been checking things out with various loads and what not..
