If what you want is ground clearance, big tires are the only way to get it. Your pumpkins are most likely the lowest point on your vehicle, and no lift kit will make them go higher. For every 2" of extra tire diameter you get, your differentials will go up 1". The cheapest way to accomodate big tires is to hack your fenders and wheelwells up. Hope it's not a new truck

The torsion bar twist and shackles are another good choice.
No matter what you choose, be prepared for increased wear on all brakes, steering, and front drive components from the extra rotating mass.
