SWEET, not a bad suggestion. I did the differential swap as one of the first changes on my truck. Going from the factory 4.57s to 4.10 ring/pinion with the easy differential swap made a noticeable improvement. At 60 mph it rpm dropped from 3,070 to 2,755 per this
calculator. However I wanted more, hence the change to a .72 5th gear T5. In hinesight, I wish I'd tried the T5 first. With the 4.57s I think it'd be about the perfect set-up. Unfortunatly the original gears in my truck had pits on the ring gear and howled excessively, another reason I changed differentials. I've been too lazy since to source a better set to check my theory.
Added in edit; On second thought I do have another T5 in the corner with a .83 overdrive, with the 4.10 gears it'd be as good as what I proposed above......Hummmmmm. Another rainy day project I'll likely never get too.
