Dunks has done a couple things to my 2005 F350 with the 6.0L Diesel. I had them do a lift and body mounts in separate visits. When doing the lift they found some other issues, called me and walked through them, gave me options and I had them fix everything. The work was top notch, the truck drives fantastic, and they led me to the right parts. There's a few different options on lifts for this truck and they recommended BDS, it rides so much better than friends trucks with same lift height, 4 link style. They know what they are doing, and do good work. Definitely will take it back, will be looking for advice on fueling system upgrades, blue spring vs. regulated return, and some other items.
