Thread: Gear ratio

Gears would be faster and cheaper, as long as the rest of the axle is in good condition. In that case you can fit almost any gear in to it as long as its from a similar model year. It depends on the size of the rear end to, not just the ratio. For instance my '05 has a 3.55 gear ratio and the size is 8.8", they also offered a 9" rear end during the same year. Find out the size of your rear end and that'll help you figure out what ratio you can fit in there.

I believe it is 9" but I'll probably double check tomorrow but what would be higher, the 2:75, 3:00, or 3:50?

The higher the number, the higher the ratio and the more power (torque) you'll get. The lower the number though, and the less power but more MPG's you'll get.

Oh lol. Gear ratio is the only thing that confuses me all the time

So if I have a lower gear ratio would I be able to go faster or is it if I have a higher gear ratio?

It's all good, and it's kind of a middle ground thing. Too high of a gear ratio and you'll have a lot of torque but be putting extra strain on the engine to get up to speed, slowing you down basically. Too low of a ratio and you won't have enough torque to get you up and going fast enough. You gotta find the happy medium.

Your right and all, but aint it the higher the number the lower the gear and vice versa?

Idk, its kinda confusing lol. But the higher the gear ratio number, the more teeth the bigger gear has compared to the smaller gear. At the moment the technical names for these gears elude me lol.

Ring and pinion

There we go, I almost said rack and pinion lol. I knew that didn't sound right because that's for power steering.
