I have a set of 440 shocks and one is leaking. They have a lifetime warranty. I called Progressive Suspension and they said the 440s have been discontinued. They dont have the replacement parts to fix them. They will replace them with the 444s for free if I have the receipt.
Here is the dilemma, I have moved since purchasing the 440 shocks and I cant find the receipt for them.
Does any one have a receipt or maybe a copy of a receipt they would be willing to part with?
If you have any other ideas, they would be greatly appreciated.

Thank you very much,
Chuck aka F6BANGER
