4.88 gears with 33s on a Rubi

Has anyone put 4.88 gears with 33s ? I have a Rubi Unlimited with auto. It seems like it would help balance out the overdrive and give more power.

It lets the engine operate more in it's powerband, but gears (OBVIOUSLY!) do NOT increase the engine's power. The engine's more efficient with the proper gearing.

It's a nice combo if you have an overdrive tranny.

with those gears you will definately have some serious torque....and i dont mean likee your engines hp will change, but you will feel more power at lower rpms, bcause your gearing is changed....so dont quote me and tell me im wrong...

What about the transfer case?

I think that would change low range to an equivalent 4.5 to 1 . Would that be a problem?

It wouldn't change your low range, it would only change your ending ratio. You need to multiply the three ratios to get your end ratio, but your Rubicon transfer case will still be 4:1. You multiply the ratio of your transmission gear by the ratio of your transfer case by the ratio of your axle. So yours would be 4.88 x 4 x (transmission ratio).

For those running 4.88s, with the auto, what kind of RPM do you have in OD? I was going to go 4.56, but now I'm leaning toward 4.88 with my 33s for now. (35" tires in a couple years, don't want to regear again).

Actually, power depends on leverage and the deeper gears have more leverage with the same engine/tranny, so yes, there will be more power at the wheels, which is all you feel anyway.

Umm acutally I am not wrong. I consider power to be a combination of HP and torque.....Gears multiply the torque......Nice try though

I "consider" power to be HP at the engine. Gears don't change that, last time I checked.

Thanks though.
