Gear upgraded, 3.08 to 4.10
I just upgraded the gear in my Suburban from 3.08 to 4.10! Still need to go to a speedo shop to get the speedometer calibrated. First drive today, it's feels quite a bit more responsive though it's...

After first gear you may not find much difference.
The 4.1 gives nearly the same gear ratios as going down one gear with the 3.08 after first gear and you lose the overdrive.
3.08 4.1 Equlivant
2.97 3.95 1st
2.31 3.08 2nd
1.57 2.09 3rd
1.18 1.57 4th
1 1.33 5th
0.75 1.00 6th
Note how close the gear ratios above first gear are.
Not even close! Each ratio becomes more efficient at towing a heavier load. Dropping a gear does nothing!
You do not see the same numbers that I do.
6 th gear with 4.1 is the exact same ratio as 5 th gear with 3.08.
4 th gear with 4.1 is also exact same ratio as 3 rd gear with the 3.08.
The others are very close except of course 1 st gear which is almost never used beyond 5 mph.
The 6 speed auto with a torque converter has more than enough torque in first gear regardless the axle ratio.
