Do you have leaf spring suspension or torsion axle? If you have leaf springs, you can have the springs relocated to the top of the axle rather than being under. It is generally referred to as "flipping the axles" although that term is not really accurate.
If you have the torsion axles, you can either have a sub frame installed or replace the axles with a different drop arm angle.
