Better towing performance
I recently purchased a 2015 1500 Z71 LT. It has the 5.3L with 3.42 gears, I got the truck because of the deal the dealership made me since it was a demo truck and only had 3400 miles on it. I pull a camper with a 7400 GVWR. I have added the firestone helper bags to the rear-end, a cold air intake, and a Bully Dog GT Platinum Gas tuner. Since I am towing a heavier camper, would it be beneficial for me to swap the 3.42 gears out with some 3.73 and add an aftermarket tranny cooler.
