What gear size do I need for my 2.7l

I have the 5 speed 2.7l with 285/70/17 and I'm just getting tired of having to down shift all the time when I go up a slight incline on the hwy. what's a good brand and sizing for getting regeared for more power and better fuel mileage?

 

I just ordered some 4.88 for my 2.7

 

Screw gear. BOOOOOST

 

Have you installed them yet? Im wanting to know how you liking the gears..

 

285/70/17

I live in Vancouver,WA

 

if you wheel often 4.88, otherwise 4.56 should make a nice difference while still providing nice mileage

 

What of difference should i be seeing?
Would i have to change the front diff gears and the rear gears or can i just pass with just changing the rear gears?
Any suggestions on what brand is good?

 

I just ordered my 4.88's today. Also ordered front and rear ARB's and a fresh set of 255/85-16 KM2's.

 

You would have to change front and rear if you ever wanted to use your 4x4 again. Good news is you have 4.10 gears stock and will be able to sell those here to recoup some cash.
You're not goingbto see much more than 1 or 2 more mpg with a regear. The real killed to your mpgs is the weight of the tires.

 

Yeah i have the stock 4.10 gears..
I just want to gain some more power back, the gas millage gain will be somewhat helpful.

 

Overall would this be worth the money and struggle to do this mod to my truck???
Will i notice a day and night or a sight difference in power??

 

Day and night difference, as much as a 2.7 can do anyways. It'll be more like it was before you got 33's

But you're looking at about 1-2k depending on labor.

 

even when i had my 235/85/16's i found i had to gear down a lot for any incline, this is normal with the 4 banger.
