I have the suspension stuff 2" lift for a D1 in my truck. I have dobbinson coils with suspension stuff shocks. In the front I have the heavy duty 40mm lifted coils (I have a bullbar and a dual battery system) and in the back I have medium duty coils (I have a roof top tent and fridge and gear etc). The ride was very choppy and not very comfy when I first installed the kit. However, once I put the roof top tent on and the fridge in, the ride is perfect. Their shocks are great and they are cheap as well.. Very solid units. I have had the kit in a little longer then six months and it works a treat. Good flex, good on road manners, and does not skip and jump around off road gravel work either. However, I did set it up to be a tourer and not a flex weapon.. :) Hope this helps
