well heres the thing ive got 33's and 4.56's with my 3.0 if i ran 34's that wouldnt be pushing it but would help out alot on the interstate just a hair bigger or find a 35 thats small thats around the 34in mark to lower the rpms on the interstate for a tad bit better interstate mileage

My last thought is, with the OHV and 35's, with highway driving, 4.56's will work great.
I'm thinking back how my ranger (4.0L OHV 5 spd) was with 3.73's and 33's. I think 4.10's would have worked well with it for highway driving. I remember how the OHV doesn't like to rev high and feels like it's about to explode around 4k RPM, but has plenty of low end torque.
Mine came stock with 3.73's and 31" tires. If you try to bring it back to stock with 35's, you would need 4.21 gears (don't exist). So 4.56 gears will bring you a little lower than stock helping with the extra weight, without revving too high on the freeway.


The SOHC is a different beast, it pulls great once you get the revs up, but wants a lower gear to get moving.
^^this man speaks the truth.

4.56's. like said above 4.88's will be too much for highway use.

Something to remember..

If your working your engine ( as you are with your 3.73's ) , your going to use more fuel at initial movement/acceleration. a lower gear will take less fuel as torque replication is more easily achieved.

In city driving, I average about 8-9 MPG, on the highways, I have seen over 30mpg with 3.31's and a better OD gear.

Its all about burn rate and energy expelled -vs- the friction of the drivetrain.

Lower gears= less resistance.
