Anyone used this lift kit or know anything about it. Looking to do the lift before winter. I know you get what you pay for but i'm new to body lifts. Placed new suspension under plenty of cars with no problem. I see they come with front bumper brackets. My front bumper is a little smashed in on the driver's side (stupid donuts in the snow). Will i have problems with the mounting. I work at a dealer so i'll be using a lift & air tools FYI. Any info appreciated. 99 Tahoe 4wd 4dr
