QA1 coil over conversion... upper and lower arms will be needed.. period when you go this low with these little trucks the control arms love to beat the frames in front of the spring pockets like a redheaded step child.
you have to do it either way with bags or coil overs
just depends on how low he wants to go.. down fall to being stupid low with bags is the shock placement. also along with tire height, anything above 25"s the stock inner fenders will have to be yanked. and this needs to happen in suit of such.
here was the truck when bagged notched stock lower arms.
