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 ...

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.
Yes, that is certainly the truth and you captured my thoughts perfectly. Off the line, the Denali probably felt quicker. At highway speeds, because it's wrapped up a bit at 2500 RPM's I can hit the gas and it'll jump and accelerate without downshifting much better. With that perspective in mind, this rig will certainly pull the camper down the highway with much more ease, that's for sure. And after all, that's the true reason I bought. I work from home, so I don't even need to drive it every day if I don't want to.
