Anyone ever do a 3.73 swap on the 4th gens. Looking at getting rid of the 3.42. It’s a 2018 3500 srw with Aisin. I have a 21 HO as well and they are the same build tires and wheels. Just different gears and power is the difference reason I ask is I notice when I drive the 18 it doesn’t pull and drive as well as the 21 and this has been something I have thought about for a while.
