What gearing do you run?

Im building my GM 12 bolt which has 3.73's. Im wanting to run 35's-37's and was wondeirng what gears yall would run with 35's-37's. Would the 3.73's work, I just wouldnt have my top speeds anymore?

Like you said you wont have any top end and your get up and go is not going to be that great with that big of a tire. If you want to wheel it that 6 cylinder might have some trouble getting it around the trails with those big meats.

i have run 35's with 3.55 gears. it did ok on the trail, did rear good on the highway but it was in a f-150. for 35's 4.10s are great because they do good on the trail and on the highway. are you running a automatic or stick?

[vabronconut]

just thought i would add, i have 4.88's in my axles, with 38 in tires. and it will be stricktly a trail truck, i don't think it will be worth a damn on the highway or the engine will be screaming.
