Gear ratio

What ratio should I put in to increase take off

 

[Dirtman]

Lower than what you have now...

In other words; you haven’t given us enough information to answer your question. Look at the axle code on your door sticker, or better yet, look at the tag on your differential so we can figure out what your current gear ratio and axle is. Another factor is what size tires you have. That’s on the sidewall of the tire. And, what engine?

4.10’s are a good starting point- with stock size tires. The bigger the tire, the deeper (lower) the gear ratio.

If you aren't experience with gear ratios: higher numerical ratios are lower gears, lower numbers mean higher gears. I think that came from the distant past when cars came from the factory with low gears to help get cars moving with very little power- a 1932 Ford V8 made 65 hp,for example. My friend's 35 Ford pickup had 4.88 gears and I swapped in 3.54'a so he could go over 50 mph- 3.54's were "higher" gears than 4.88's because the top speed was higher. Intuitively, lower gears should hurt the gas mileage because of higher RPM's, in hilly areas like NH lower gears can actually help the mileage because the engine doesn't have to work as hard climbing hills.
