Front / Rear Spring Preload Adjustment
The factory setting is appropriate for nearly all riding conditions. If desired, the suspension may be adjusted to maintain vehicle clearance height when carrying loads. Adjusting the suspension may change vehicle handling. 

Important: The distance between the main preload spring (top ring) and the cross-over rings (middle rings) should be constant. If you move the main preload ring, you will need to move the cross-over rings an equal amount. The cross-over rings need to be locked tight after any adjustment is made. To lock the cross-over rings, take a punch and hammer to hit each side so the rings jam together. If the cross-over rings are not locked down tight, damage to the shock may occur. 

To adjust the preload, do the following:

1. Elevate the vehicle to allow the suspension to fully extend. 

2. Turn the adjusting ring to the left to add preload. Turn the adjusting ring to the right to remove preload. 

Uneven adjustment may cause poor handling of the vehicle. Always adjust both the left and right spring preloads equally or have your Polaris Dealer or qualified person perform the adjustments. 

Front / Rear Shock Compression Adjustment (Non-DYNAMIX Vehicles)
The compression damping clicker knob is located at the top of the shock reservoir. 

1. Turn the clicker clockwise to increase compression damping. 

2. Turn the clicker counterclockwise to decrease compression damping.
