I bought a 1979 Ford Front axle (8-lug) with 4.09 gear ratio. My rear dually axle has 3.73 gear ratio. What I am wondering is which one to change to match the other.
I have a 5-speed tranny with overdrive 0.73 ratio. If I am running 35 inch tires would I want the 3.73 or the 4.09? I am looking for driveability with towing/hauling capacity on occasion.
Any advice or experience would be appreciated.
Thanks,
Craig
