Right now I've got a 2" BL on my truck w/ 285/75/16 BFG at's. They rub slightly so I was thinking of either adding a PML or going all out with a 3" SL. I've got the money for the SL, and know if I go with it I'll also need to upgrade the steering system. My major concern is maintenance. I really don't want to do anything that is going to need constant upkeep or that I'm going to have to worry about. 99% of my driving will be on the road, which I would assume affects the wear on both the lift and steering. So what should I look at doing?
