Re: 12 bolt truck rear.
@ 70 mph = 2294 rpm 3.73 gear.
@ 70 mph = 2104 rpm 3.42 gear.
reason is most likely some motor combos pull better with a bit of a drag load on the system . my 1 atv if i swap in a smaller engine sprocket the motor just winds up . if i go 1 tooth up in sprocket size on the engine she PULLS like a freight train
