Sorry I forgot to clarify but the radius arm type is what I meant. I'm really looking at them for my tow rig now that I swapped on a set of Superduty HD springs to help balance the load capacity. With Trooper in tow and a bed full of gear/junk the truck performs flawlessly yet empty it hops like crazy I guess due to the super stiff new springs. 16.5" commercial duty high mileage tires dont help either. However like all my rigs (car truck etc.) it does see its fair share of trail runnin and I didnt want to screw up what little flex I had. Now my wheel hopping Trooper might get a set as well.

Thanks again for confirming my thoughts on them.
