I sent my raptor to Hennessy and I had it leveled. Everything feels the same with drive. With leveling it probably lifted it a couple of inches. I didn't want to change the height of the truck, because I wanted to be able to take truck to airport and other parking garages. Looks awesome very happy about it. Had several other things done as well.
TMX (Texas Motorworx) lifted my truck with 1.5" collars to make it level. I think it looks great and there is no difference driving it. They also added the Baja Design Pro lights which are great!
I just got the ones from CJ Pony that'll level my truck but a buddy of mine leveled his and he's insisting that I don't go do it because he got flashed all the time by oncoming traffic and even got pulled over by a cop who didn't like his lights being in his eyes.
I posted these pic's on another conversation but I thought the 1.5" lift was just right and I love the Baja Design Pro lights!
No, but I have not driven much at night since I had it done. Many trucks in the Dallas area are leveled and I have not heard of any problems. I will ask the company that did the lift if they recommend adjusting the lights after the lift.
