Overdrive options

Well I'll tell you guys...........while you are all pattig yourselves on the back, there ARE inherent problems running too low a gear with a tall OD. That driveshaft is STILL spinning whatever RPM it was OD or now, and that ring and pinion are STILL REALLY churnin up the oil and makin' HEAT. Will "in a previous life" experience with friends and Jeeps with stuff like 5:38s (not all that low with big *** tall tires!!) There CAN be problems doin' "80" on the hiway!!


Must be why my cummins ram has a double OD and 4.10 gears from the factory and 258k miles.

This theory has been brought up before and dispelled by numerous professionals in the business.
