i am thinking about 4.10 to 4.30 or so, i would like to turbo or supercharger the truck sometime, i love the torque of a supercharger, especially the kenne Bell. i might go to 35 in tires but no bigger than that, for not i think gears and tune would be the best. i would like to put a built 6.0 with kenne bell supercharger, and a built to the wall 4L80e trans. but that is later. where to get gears at? what brand of gears should i get?
