I have been looking at gear swaps. Test drove a 3.08 vs 3.42 Tahoe and cant tell much difference. My burb has 3.08 gears. At 80+ on fwy it’s great. But accelerating from 50 to 70 you almost must hit the downshift. So I have thought about a full axle swap for $ factor should be cheaper. Maybe a z71 rear with 3.73 or just biting the bullet and throwing new gears in the current one. I know the swap in current axle will take more money and time yet there is nothing wrong w the axle in there now. So I ask. Those who have swapped what did you find the drivability to be like afterward and towing? Bang for the buck? Is the difference to 3.73 barely enough to be noticed and would you just throw money at some more Hp? The xl/burb platform is some extra weight for sure. But dang it drives good. And honestly can’t fully justify the extra 15k to upgrade to a Denali for the 6.2 right now since mine is paid off.
