You want to raise the front? You could always try a spacer somewhere but I would opt for changing the springs for longer ones. There are spring specialists out there that can mod yours or supply new to your specification.
I have always
lowered vehicles for the cool look and my HiArse was no exception. I cut one turn out of the front springs and fitted 2 and a half inch lowering blocks and longer u-bolts at the rear. Cornered like it was on rails and ended up low enough to fit into my garage.
