Gear ratio question.
Yes, I have searched.
The charts say that with a 32"tire my xj ratio for an overdrive automatic should be at least 4:88 gears. What are your thoughts? Thanks |
year of your jeep and tcase would've been helpful info. looks like aw4/231 on 32's will do 2100rpm @ 65mph with 4.10 gears
this is almost exactly stock rpm's |
Ya 4.10s would be good to keep it stock, if you want more torque you could do 4.56s
|

Thanks guys. So the chart was pretty close. I would like it lower than stock. So 4:56 or 4:88's seems spot on for me.
You just saved me some money. I almost bought a 3:73 set. Thanks |

Would you need to change both carriers? I'm considering this too while I'm in there to replace leaky seals.

Depends on which axles you have.
|
I say 4.56

4.10 - going with a different ratio will affect your drive... You also need to change the speedo gear.
