I'd like to know the effect of a different gear ratio on both diff. On torque curb and on towing comportment. I know that people who usualy tow prefer to use a bigger diff. ratio (commonly a 4-10 or close to that on american full size pickup). I tow about 30 - 40% of the time with my truck, so I'm looking for a way to make it a bit easyer for tranny, diff and engine, or at least increase a bit it ability to make a load moving. And get it better on hills towing.

I'm looking to get a Cortex Superchip, but it only increase a bit my power. I don't like using full throttle when towing, so I cannot expect something great of that. My real desire is to get torque curb down a bit at wheels, to get more torq, a bit more revs at a slower cruising speed without speed variation on every little bump on the road, and when facing wind. and off course possibly a better towing gas mileage.

I've a v6 kc SE with 5spd auto.

Yeah it's a 4x4...

The parts I would need are?
I'm not knowing alot about differentials and I don't realy know what to do to change ratio. Can I just change gears, or I must change all differential, or all axle?

I know that a larger ratio mean, with the same wheel sise, a greater number of turn fron driving to make a1 total rev. ohf the wheel, and at a same engine rev. a larger ratio mean less speed with same wheel size. Beside that...

If I understant well, I can change the gears in my rear diff, in the same "case" but will need to change the entire module in front?

you would need the master install kit as well as the ring and pinion for the rear , since you are 4wd 3.73 ratio is really your only way to go
( you need to have a professional install them )
the front is easier to install as an assembly
