Ive got a 05 screw lariat 4x4 i just put a rough country 2.5 level kit with the 1 inch rear block and shocks on. I pull a trailer daily for work and a boat all summer. I need a little more lift in the back but was unsure if add a leaf would mean i have to shim drive shaft or do anything else. I just want the back a little bit higher. Any advice is appreciated
thanks
