They are night and day better on the highway than the stock shocks with the RPG collar. I like mine a bit on the stiffer side so the collar was what I was looking for over stock. Stock shocks were too soft and no pre-load so I was bottoming out off road pretty bad. The collars made a big difference in helping that, but it did stiffen the on road ride a bit. The new Kings on road feel like the shock did stock, nice and soft. I tested it on some pretty big dips and was overwhelmed at how the truck took the hit and I got zero bounce like I did with the stock shocks with the collar. It just hit the dip and I barely moved in the truck. I have the Kings set very soft with the compression adjustment now. I will have 2 settings once I get it off road and test it. One setting will be for on road, and the other for off road.
