If you are purchasing a 2" alignment kit, please note that you will need to cut the top of the bearing rack studs to ensure the assembly is properly bolted. This step, which they don't mention, adds another 45 minutes to the first page to take it all apart and start over. This 2" kit added 3-1/8" of travel to the front of my 2018 Silverado 1500. I wouldn't go for a 3 inch rise as I think that will be too high in the long run. I really hoped I didn't have to cut any factory parts to complete this install which is why they got 1 star.
