my '01 cummins powered 2500 is currently running 32" tires on the original 3.54 gear ratio. even with the mods i find the performance to be a bit lackluster due to the gear ratio.
im preparing to upgrade to 35" tires, and am trying to decide between
3.73 and 4.10 gears. i already have set of 4.10 gears that i bought for another truck that i dont own anymore (the truck in my last thread about the 3500 giving me fits, i unloaded it this past weekend). i could use these gears in my 2500, or i could swap them out for 3.73.what say you?
thanks,
