After looking at the Rhino axles in your pic. I went out and took another look at the OEM axles on my P500. Surprisingly, my axles look more like the Rhinos than your stock axle. Could this have been a mid production improvement? Or, could Honda have "outsourced" axles from Rhino? You've had yours longer than me, so it is a possibility. I worked at a Tenneco Automotive production facility to pay my way through college. The only difference between MOPAR, OEM Ford, NAPA, and Monroe shocks is paint colors and decals. Honda could have switched suppliers mid run.
