Maybe numerically it looks good on paper but when you throw in a much larger rolling mass (tires) + added wind resistance, the 3.73's might be a bit high.

I'd probably go 4.10's but I don't know how your tranny effects the end result compared to mine.

Right now I have a 14 SF axle that will eventually be 4.10's sitting in the garage waiting to be installed.....

im thinking that im gonna try and pick up a 3/4 ton set dana 44 14 bolt with 4.10s already in them. figured since axles will be out to do lift might as well swap them and have the gears plus stronger axles
