I have a chevy 1-ton 4x4 crew cab that I removed the bed from and shortened the frame. I installed a skyjacker 8" lift. The rear spring packs were made to be used on a 1-ton truck that was used as a truck. I no longer have anything back there to create weight but a spare tire and gas tank. I want to remove some of the leafs to create more flex. Has anyone done this before? How many leafs and which ones should I start with? What do I need to consider when doing this?
