Mine has 3.55 gears front and rear. Crappy fuel mileage , I do a lot of highway driving and no hauling/pulling trailers yet, would 4.11 be better or what ???
I need to replace axle seals soon and might as well do gears while its apart.

 

No towing and a lot of highway, you're better off with 3.55's.

 

I plan on towing around a little boat eventually and I mostly do town driving what do you think is a better gearing in my situation ?

 

I'm betting the 3.55 was stock, and some previous owner re-geared. Yeah, not a cheap endeavor. Since you only need to do one end, stick with the 4.10/4.11, whatever. MUCH better gearing for a truck.

 

Yeah I'm confused with why the ring says 4.11 haha anyways yeah I'm thinking its easier to change the gearing in the rear since I've done it once already lol

Also I don't think it'll change the answer you gave but my truck is lifted 6" and 35" tires

 

Yep. That makes it even MORE likely that the previous owner re-geared. I am surprised he didn't go to 4.56 though.... Oh well. Re-gear the rear to 4.10, and be happy.

 

Another great outcome here ! Thanks everyone and especially HeyYou haha

 

Kind of an unpleasant pleasant surprise...

 

That's what I'm wondering with 8" of lift and running 35x12.50x15s on mine, mpgs suck with 3.55s

 

big lift killing aerodynamics? check.

heavy tires? check.

you can change gears all you want, but there is no bringing back that mpg...

I've learned to appreciate the cheap gas with my 3.55s and 35s. 10mpg with the 5.9.
