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...

I have been milling around in my head whether or not it would be more effective to change gear ratio from 3.73 to 4.10 in my Yukon XL 2500 or to work on improving engine torque and HP at the RPMs I'm currently at. It would only be a 2-300 RPM change and I'm not sure that would be enough for my 4 speed trans to make a difference.
It made a huge difference in my V-10. I went from 3.73 to 4.30. 3rd gear runs about 400rpm higher but closer to where it's making its power. I never really could run in OD with the 3.73's. With the 4.30 I am able to run in OD with no issues. It only kicks into 3rd on the bigger hills. Worth every penny!
