The Arctic Cat Pro Cross rear skidframe, especially the 137" length, has dramatically excessive low and high speed rebound damping. From 2014 right up to 2018, we find that the rear suspension recovers far too slowly after a bump of any displacement. The Yamaha Vipers are the same. The base model sleds with the Fox Zero Pro shocks (no adjustability) AND the newer Fox QS3s are both affected by this calibration.
