As I have only rode in a truck equipped with KORE, and hearing Lorenz is better, I now have to say that I would go with the Lorenz. This is based on the KORE having a very nice ride overall.snowaholic said:They are all 3 very good supensions. There was an artical on a complete testing write up that 3 TDR members did for comparison of the 3. The end results were Lorenz #1, Kore and Carli I think tied for #2. They tested everything from Highway to Offroad. I went with Kore, got a good deal and some extra included stuff that were options on the other kits. I would not hesite to use any of the 3, all have a very good rep, and are hands down better than any of the other Mass Susp dealers.
