Opinions for gearing

Yes I have already read the countless articles on regearing, but every application is different.

8inch lift, toyos 37 just like in the sig my gears now are 3.73. My fuel mileage is horrible and I know I need to regear but not sure if I want 4.56 or 4.30 so your opinions are important to me so post away.

Some more details: I pull about a 7,000 pound trailer 3 days out of a normal 5 day work week sometimes more depending on work load.
What should I see as far as fuel mileage when I switch? Currently im getting 8 in town with trailer 10 without. I know I should worry about mileage with a truck but the fuel cost at the end of the month is killing me.

Thanks for any imput

I'd go for 4.30's myself. That should help you out some.

Well, pulling maybe the 4.56, but id say youd only need the 4.30's with the 38's. But if you plan on going any bigger???

I do plan on going bigger but no bigger then 39s....They should have a gear in the middle to solve this issue like 4.44s

When you regeared did you see a performance gain? and did your mpgs change?

I don't remember what was stock in 05 but it was apx. 32 so with your 37s you'll need 4.30s to get BACK to 3.73s and if you go to 39s than go to 4.56s to maintain apx a 3.73 final drive ratio.
I'm running 4.30s with 33.5s which puts me at an actual 4.11 final drive.
