what size tire? the 4.10s will be much nicer with the 80es first gear...but the higher OD gear kind of hurts too, depending on tire size. How much highway, etc? Personally, i like deep gears for DD purposes, but mines mostly street driving.
255 works out to be just about 29" tall, which will put me about 2250?You're going to be at 2400rpm @ 70mph with a 30" tire and a 4.10:1 with the 0.75:1 OD of the 80E. Bit high for my taste on cruise RPM.

I wonder if they make somewhere in the middle of the road 3.90s for these trucks, like they do mustangs. search time.
Whoops, duh.. :bawl:Uh no, smaller diameter tire (rotates faster) = higher RPM. 2494rpm @ 70mph.
Yes, a 3.90:1 gear set is made.
