I have a 2000 Dodge Ram 2500 Diesel 4x4. The truck, like most of these trucks, wanders when driving on the road and even more so on the freeway. I was hoping this would fix the problem. This stabilizer helped fix the problem about 75-80%. The truck still scrapes a bit but it's significantly better than before, I was hoping this would fix the problem completely. All in all a very good product, well made, comes with grade 8 screws which is great. The instructions even list screw sizes and tightening torques! Thank you BD Diesel.
