I installed Bilstein 6112/5160 and Bilstein control arms to give the front a 1.2" lift. I think they should have come this way stock. I get that it's a truck, but GM's off-road oriented truck probably shouldn't have the same rake as a regular truck and a little bigger tire. It's not perfectly level and I'm good with that so I can still use it as a truck. Currently have 285/65-20 ridge grapplers that need to be replaced soon. These fit stock but needed a 1/2" wheel spacer to clear new control arms and a mud flap delete after spacer.
