thanks bud! I forgot to mention I have borla headers all the way. I'm actually looking into changin' the gears although I have that supercharger I can't spin the tires. Ya know what I mean! My question is what would be a good set for my rig, I'm running 20's with 305x50.

Thanks

Reprogrammed PCM will help...and I'm not talking about doing so via handheld programmers like Hypertech.

what do you have now 3.73 or 4.10's

if you want to spin the tires a set of traction springs or bars will help, they will keep the leaf springs from tristing and sucking up the initial power sent to the tires.

other than that a higher rpm torque converter, get a 2000 rpm and you will probably have a hard time not spinning the tires ,thats when my s/c 5.3 really starts to pull.

also depends on tire compound, i had bridgestone steeltech 285/75r16 they wear a hard compound and broke loose pretty easy , after lift i put on bgf mud terrain 315/75r16 and they are so soft i can seldom braek them loose without serious abuse even after putting in 4.56 gears.
