90 K1500 4x4. I put a 3” suspension lift on. Now the truck has 3 1/2” of rake in it and a ton of pos camber. I’m keyed up to 1/2” off the stops. A couple questions. 1- why so much rake? 2- will that camber adjust out or do I need those after market control arms that correct the geometry and ball joint angle? Any help greatly appreciated!
