Hey yall I have 3.73 gears in my truck right now what would give the best upgrade as far as acceleration and comfort on the highway the thing is i am getting larger tires put on here pretty soon upgrading to 31x10.5. I need to know if the 4.10s are the way to go or 4.56. I would like yalls opinion on the matter.

4.10's and 31 are about perfect for mileage if you are doing mostly freeway.

4.56's would be great for around town driving and towing/hill roads.

If you are considering larger tires like 33's, also consider 4.88's.

I am assuming you have a 3.0L.

if you have a 4.0 keep the gears you have now im getting around 19-20 mpg on the highway. and thats the set up i have in my truck

also i wouldnt run more than a 4.56 with 33s

we need to know what motor you have.

I have a 3.0L will i notice much of a difference when upgrading to 4.10s I heard from a friend of mine that it should improve better with larger tires. With 4.10s or 4.56 gears on highway wont my RPMs read high what i dont want is to put too much stress on the engine. I just want better acceleration you know
