I've seen these (note the parts pointed to by the red arrows in the image) on the landing gear struts of Super Cubs and plenty of other STOL bush planes with large tundra tires. It looks like maybe just an aerodynamic fairing on the gas tube/strut of the landing gear but I'm wondering why on every example I've seen of this, the aerodynamic shapes are angled differently (one is more "up" than the other). What is this if I'm wrong about what it is and most of all why are they always angled differently? Is this to try and help with adverse yaw or something?
You can also see them in this video here (note that they, too, like all I've seen, are angled differently): FlightChops Super Cub
