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 depends upon where you find you are lacking. For example, if your vehicle shifts in and out of overdrive on rolling hills or with a light headwind, that 2-300rpm may be the difference in keeping it in the higher gear. If you're looking to accelerate quicker onto the freeway, improving the engine may be the better option.
