i have a 04 f150 4x4 supercrew with a leveling kit right now... i was wonderin if i could possibly throw this kit on and possibly fit 35s or if i should just go with the body lift with 35s?

u would should just get the body lift. Those are leveling shocks and since you already have a spacer they would do you no good. The angles would just not work with your control arms

RIght. You cannot combine a leveling kit and lift shocks. I'd suggest adding a 3 inch Performance Accessories body lift to fit 35's.

agreed id just go with a 3'' Body Lift and then after that if you wanna go higher then add a suspension lift. but those shocks wont work unless you remove the spacer..but in the end it wont make it any higher with either so just the body lift or suspension lift is what you need
