hey im trying to fit 31 " mud terrain of my brothers jeep ( he got 34 super swamper tsl's) im tryin to find the easiest and cheapest way to fit them... im thinking about buying shackles for the rear but im not sure what to do to the front... becaue i dont want to crank the t-bars, its gunna be my daily driver to school (as soon as the days over we usually hit the trails) ... but i have found some 2 and 3 " lift springs and im not sure if these will actually give me li\ft and work .. but then i also found torsion keys and im not too sure how these would work ... would they be the same as cranking the bars ? would they damage the joints as well ?.... any help would be appreciated thanks ... Josh R.

i have a 96 gmc jimmy by the way...

 

Would have been best if you posted this in the lifting section under Suspension Tech section, I don't know much about suspension lifts but with the spring you may have to have shocks... I would go with a body lift because it doesn't change the ride characteristics much.
