DML FAQ : Chassis : How does the Roadmaster Active Suspension work on a 4x4?
I have had it on my 2000 4X4 for about a year now and really like it. Installation was very easy.Other than the supercharger it's one of the best mods. I've done. It took out all of the wheel hop I was having and I don't have to worry about axle wrap with these installed.
