I might be interested if you still have this for sale. I need part number E80-23-006-02-22 for a 2017 silverado 1500 4x4 crew cab. Let me know. Thanks

I am looking for a lift that actually increases wheel travel. The lift amount I'm looking for is 2"-4". I don't want a spacer or block as it does nothing to increase suspension performance. Has anyone added coil springs that are longer to the front of their truck? Did you have to get different upper control arms and/or shocks for the lift? I know that there are long travel kits out there but I'm looking for some mods that increase performance with a small amount of lift. Thanks in advance for any help.
