how does lift effect powertrain?

[Jason Lister]

my 2015 serria 1500 has P285/45R22 A/T tires i want to get some mud tires P285/55R22 to do this i need smaller rims or lift i wanted to add 4 inch lift front and back but looking at the truck if i add blocks to the springs i dont see how it would effect the drivetrain or warrenty for that matter.

 

does anyone have any insight?
