If you happen to have one of the 2019 Polaris Indy XC 129” sleds, then you have a Walker Evans Velocity Series shock on the rear torque arm, and a compression-adjustable Piggyback Walker Evans with a 2” body on the front torque arm. One thing many riders had happen last winter was for one or both of the compression adjuster knobs would fall off. Seems during assembly of the shock and installation of the adjuster knob that thread locker was not applied, the screw wasn’t tightened, or both.
Point is, if you have one of these sleds you want to first check and see if all of the adjuster knobs are still in place. If not, get them and a new screw ordered. Most dealers will be still be able to warranty this for you if you act fast. If the knobs are still there, you might want to check the tension of the screw to make sure they don’t fall off. Might even want to remove the screw if it’s loose and apply some thread locking compound (we suggest blue) before installing and tightening. This was happening mostly on both of the shocks in the rear suspension on the 2019 Indy XC models.
