Yes it will help, but will it help $3000 worth? .

3000ish or more is just the strt, lower fuel milage for the rest of the trucks life on empty or towing. accellerated enging wear from higher RPM.

Best way to do it is big torque low rpm in my opinion, if you could aford it adding a turbo set up would be the most efficent way to go but has issues in its own. or if its time to buy a new truck soon anyways put up with it and get a diesel. (sorry didnt see that it is a 2017, so i guess thats not an option unless your leasing and its time for a trade in. some times dealerships will give you a good buy back on a relitively new truck, might be somthing to check into. the 6.2L is not realy a tow monster motor to start with.

Obviously you have never done this swap and know what it can do! It will not get worse mileage towing, in fact it will go up approx .5 mpg towing. In town non towing driving it will go down, but marginally. But non towing city/hwy will go up. Solo hey you may lose .5 mpg. It’s not going to wear out the engine any faster. If it does the only difference is hours or converted maybe a couple thousand miles during the engines life. So if the engine were to last 200k miles with 3.73’s it may only last 198k with 4.30’s.

Love how people comment on things they know nothing about!
