G56 higher ratio OD for 2007 or 2007.5???
If this has already been covered, maybe you can point me in the right direction.
The VN5600 6 speed manual has a 0.73 OD ratio and the G56 originally came out with a 0.79 OD ratio, which raised the RPM quite a bit at highway speed. For 2007, the G56 supposedly has a 0.74 OD ratio for lower RPM, but did they come out with the older 5.9L engine in the beginning of MY2007 or only with the new 2007.5 6.7L???
Thanks

There is a 3.42 ring and pinion comming out at the end of may or early june here is the contact info:
We actually have 3.42's coming in very soon. We have a long list of people waiting on them and expect them to go quickly, so we are excepting pre-orders. The gears are MFG by AAM and run $370.

I only want to change the O/D gear ratio. I think I might go to a 35" tire also. I liked my ford 6 speed but when I test drove the Dodge we just went on a side road by the dealer and I never had the truck in 6th gear. I didn't realize til I was driving home that I was revving so high. Oh well, at least it's got a Cummins.
