02 3500 dually 6sp NV5600 Rear wheel drive 3.55 ratio dana 80
Are you or do you know of anyone running 3.31 ratio gears in a dana 80?
I'm currently running 3.55's and would like to switch to 3.31's so I can run lower rpm's in 5th (1:1) gear while towing.
If you have done this I would like to hear about what you think & how your truck is performing while running 3.31's.
Thanks!
