Re: gears

your stock ratio is 3.27 so a 3.73 would be the lowest noticeable jump while maintaining gas mileage. I think the change is 12% more acceleration but not 100%

4.10s are great but will eat up more gas of course. The faster the rpms climb the faster you get to shift thats another trade off.

Re: gears

With an auto your mpg won't change much, if at all, with 3.73s. With 4.10s(and proper auto-trans recalibration) you will get better MPGs in city, and go down about 1-4mpg on HWY if you drive nicely.

Re: gears

A 4.10 gear will have few rotations before the tires start to move vs the 3.73

Re: gears

Basically a certain gear-set is a torque-multiplier. Much like how pulleys act in a rope system, allowing the same force to do greater work on an object(such as a heavy item).

What a "3.73" or "4.10" gear means is that it takes the drivshaft 3.73turns or 4.10turns respectively in order to make the rear tires turn one complete rotation. The more turns the driveshaft makes per tire revolution the less power the engine has to put out to do the same amount of work. Therefore even though the power output of the engine hasn't changed, the mere fact it uses less power makes it seem like the engine produces more power because it uses it more efficiently. Therefore you get quicker acceleration.
