I suspect most respondents who have lifted trucks report how great everything is...in the short term. How about some years and significant mileage later. How's the driveline u-joints holding up? How about the ball joints, tire wear since cornering with higher vehicle mass weight. Maybe had to up the tire pressure to compensate, and now the truck rides rougher/stiffer. Stretched brake lines still good? Anyone towing something of significance. How's that been affected? Had to buy a different hitch, make the trailer pigtail wire longer? How's working under the hood going? Had to buy a step ladder or are you already 6'6". How about the reduced gas mileage from higher wind resistance. Wasn't a big deal a few years ago, but it is now with $4 gas.
