Looking for a leveling kit for a 1999 F250 diesel. Only thing I found was the air lift system. Can anyone help?

 

Well, if you don't mind lowering the rear of the truck, then you can use the 2" spring-block replacement kit that Ford came out with. At one time, Ford was paying to have the 4" blocks replaced. But, that time has long since passed. You can still buy the kit and do it yourself... or I'm sure they'd be happy to take your money and install the kit for you.
