1500 Yukon XL Denali vs 2500 Suburban 8.1
Hello all, As you can see from my subject line, I'm contemplating making a change from my 2005 GMC Yukon XL Denali to a 2004 Chevy Suburban (2500). I'm looking for some real world comparisons ...

Going from 3.73's to 4.1's will have approx 10% more torque at the drive axles,
minus losses. That is how diff gearing works

First impressions are that power-wise, it doesn't feel much different than the H.O. 6.0 I had in the Denali.
And going from the 4L65/70E that was in his Denali to the 4L85E that is in the Suburban results in approximately a 20% decrease in first gear (3.06 down to 2.48).
ksu_j, you probably have noticed that they seem the same off the line. What about at cruising speed? I would have to think that the 8.1L/4.10 combo has the advantage in 3rd and 4th.
