Friis - I am not a truck mechanic, but I have always worked on my stuff since I was a kid. I am a mechanic though but I work on jetski's, snowmobiles, dirtbikes, and stuff like that. I never went to school though.
When it comes to the ICON lift, I am very satisfied. I bought the truck with a 6" procomp lift and it rides twice as good with the 12.5" ICON. I dont have alot of experiance with lift products, but all the components were higher quality than the procomp stuff I took off, and everthing was a perfect fit.
About the handling, it drives like a stock truck, but thats more than the just the lift. The wheels and tires, alignment, and steering stabilizers play a big part in handling also.
When I saw the door handles I had to have them. Luckly my girlfriend bought them for me, because they were $200.
