I was going to pick up my rock sliders from All Pro, but they are currently out of stock. They should have some in next week so I'll be getting them then. However, my question is should I do my planned body lift before installing the sliders? I'm wondering if I install the sliders before the lift will it create a space between the sliders and body that I won't want. I'm hoping you guys know what I mean....and as always, thanks for the help.
