I did the DSS along with the 3rd gen adjustable track bar. Things were a bit more complex for my application due to my Boss V snowplow mount, but that affected the plow mount, not the DSS or trackbar. I had to make an entirely new and different frame support for the driver's side of the snowplow mount.
The DSS I received was very poorly made and did not even come close to fitting. I had to cut it apart and weld in a spacer plate to get it to fit the steering box. The bearing mounting plate was way too low and off-center. The proper thing to do would have been to return it, but aside from the additional shipping expense, I did not have the time to wait for a different one and there was no guarantee the next one would be any better.
Once mounted, there was some improvement from the two devices, but the rest of the front suspension is so shot, along with the tires, it still feels like I have square front tires. It is a miserable truck to drive.
The 3rd gen trackbar is very expensive and I am not impressed with the amount of flex in the frame bracket and will be gusseting and welding it solid. It makes little difference whether the slop comes from a bad ball joint on the end of the stock trackbar, bad bushings in other designs, or flex in the bracket. Slop is slop.
Bottom line: Both items cost far too much for what they are and do, but they also offer the best practical solution to parts of a very bad problem. By themselves, they won't cure the dodge design, but they help a little. Dodge engineers are clearly some of the worst in the world.
In all fairness, the beancounters probably had more to say about the cheap and crappy fake dana 60 than the engineers, but the engineers and marketing yuppies are to blame for the stupid coil link suspension (very light duty) on a heavy, heavy-duty truck. Coil-link suspension is 1/2 ton, sport truck, and SUV stuff and has NO place on a heavy-duty truck.
