I have the DT Profab arms on my truck along with just about every other steering mod. My truck has a leveling kit so I went with the 1/2" longer arms that put the axle back closer to it's original location. I've had the arms on for about a year or so. Check out my recent PSC Hydro Kit Installed posting and you can see all of my other steering mods. My truck steers like a sports car with my 16:1 PSC hydro steering kit. Only problem now is having to switch to Don Thuren's track bar because my Solid Steel Products bar has weak bushings that don't last long under a load.
