Question Lifted Truck Gear Ratio's

I have a 2007 2500 Mega Cab Automatic Transmission and I have lifted it running 37 / 12.5 R17 tires and I would like to switch out my gears to 4.56's. Can anyone tell me what RPMS your running at 70 mph?

My 12 is lifted 6" on 37/12.5/17 on stock gears at 70 it's around 1800 if my mind isn't playing tricks on me. 4.56 will likely put you around 2200-2500 range on highway

Thank you, and thanks for the info.

Is anyone running 4.56 gears? If so how do you like them?

I love the DTT with Motive 4:56's on my 2wd quad running 33" diameter...

I believe the 4:56 is the single best mod you can do IMO...
