I bought a new 2021 2500 with 6.7 Cummins. I had a 5 inch lift installed so I could throw on 37 in tires. The ride quality is really good even with the large tires but I was looking for anything that would make it even better.I purchased this stabalizer shock, fit was perfect. I did have to adjust my steering wheel a tiny bit after install which only took a couple minutes, plenty of videos on howto's on that. I was mainly looking for this install to help ride quality and steering feedback while towing and going down washboard dirt roads, I can say honestly that I don't now how much its helping since I did very little testing with the stock stabalizer but, its not hurting one bit.Bottom line my truck does not pull or give me bumpy feedback while towing or in any driving scenario (on or off road) even with the 5 in lift and 37s which tells me this stabalizer is doing its job well.
