Well like the title says the trucks going to the shop to tear it down and put some 4.56 gears that i got for Christmas from my parents! I'm very fortune to have the parents i have!!

Interested to hear your before and after mileage as well as impressions.

Z71crawford

I wish I would've done 4.88s but that might have been a little to low for when i go to a 6l80e, as far as mileage I don't keep real track now all I go by is my digit readout, kinda don't wanna know lol. Ill keep y'all informed about that gear swap though, unfortunately I was told I could tow or really get into her for 500 miles but that's only a week and a half for me.

Good to hear, ive got 305/55r20s so basically the same as yours and even with a full exhaust and tune 6.0 its a dog with the 3.73 gears.

Not to hijack but my mileage fell from a mixed 16 to around 14.5 after 4.56's were installed. But it's def no longer a "dog"! I can pull my buddies 6.2 awd denaili by a truck or 2 out of the hole till 60ish. Prior to head and cam.
