Need help ordering Ultimate Dana 60's.
People will need a little more information to offer you some good suggestions. What tire size are you planning to run? Do you have an Automatic or Manual tranny? Guessing you don't have a Rubicon TC since you didn't specify.
Guessing you're probably deciding between 5.13 and 5.38?? Have you consulted the gear charts for the 3.6L? IMO, falling in the 2400-2500 rpm at interstate speeds is the sweet spot. I'm currently geared a bit low and my 3.6L w/37s hums at ~3000 rpm while on the interstate at 75mph. It's a bit much, but I don't have a 4:1 TC, so I appreciate the benefits of the gearing off road.
