I have a 2" spacers put on mine about a month ago. Took it to goodyear for a free alignment check and sure enough camber n caster were out of specs. They quoted me $369 for parts, labor, and alignment. I said give me my keys and drove away. I just recently bought CST spindles from a member here and now they're just laying on the floor since my truck still at the dealership. So I'm gonna need those cam/ caster bolts anyway. I know it's kinda a waste to have my truck align after they install the bolts but hey for $60 they quote me for alignment, I look at it as if I buy those bolts n got em install for free.
