X-2... Taller tires would do the job, put on 4 or 5" of lift and go to 33s or 35" tires.do you have a lift?
your wasting your time/money.
just to save gas? ....bad idea.
you are looking at $500 parts
another 500 hunj if ya cant install gears, im guessin ya cant, not many people try and tackle that.
and why now! gas is at an alltime low!
