Gear Set Choice... 4.88 0r 5.13's
Need some first hand help regarding gear choice on unlimited rubicon ( 4" lift, 37's)
it will be driven 80% road/highway and 20% off road. I drive a lot so I need something that has fairly decent MPG but has a solid transfer to stock rpm's and torque.
Anyone who has an opinion or any info on the gear sets and the MPG associated with each is appreciated.

With 37" tires I would go with the 5:13s. The power is reasonable. I think you would be disappointed with the power using the 4:88s. Unfortunately with 37s, 5"13s and an auto trans I only get 12-13 mpg to and from work. On the Highway I get close to 16 mpg.
