Quad rate long travel with hi/lo compression, tool-less rebound, and preload adjustment. Not sure what makes a shock "elite" or not but they've stopped using that terminology, now it's just stage 1-4 and factory shocks. This would be a stage 4 in the current terminology, but the plastic rebound nut tells me it's not the latest version of these shocks as they've switched to an anodized piece from the pictures and shocks I've seen.
What atv they are long travel for, and the setup of course needs to be filled in either from the owner or elka.
