Sorry, the kit sold. I never ran the gear down kit at low elevation, I'm guessing with the extra power you would run out of clutch at trail speeds. I have always just followed the polaris clutching chart and ran 68s in my RMK's here for 1000 to 1500 feet. They recommend the black/purple secondary spring for high elevation over 8k and the stock black for low, but I would just put in the black/purple and leave it for both elevations. I don't think it made much of a difference here.
