It didnt mess up my mounts, but the hp gains we add will eventually, lol. Just remove the bottom nut that mounts on the k member and then get a mall 2x4 and place on jack and lift driver side, we had to put close to transmission and as close as you can to engine. just remember to loosen dip stick cause install will not allow you to put vc back on with it tight. It comes out fine though. Yes when vc is off lower back down and do whatever else you need to do. Good luck on heads that you may need remove booster. just so you have plenty of room. Havent gone that far yet.
