Suspension System

Front / Rear Shock Compression Adjustment

WARNING

Be advised that the shocks contain nitrogen at high pressure. Damaged shocks could cause injury if not replaced or addressed promptly by qualified personnel.

caution

Keep other individuals away from the vehicle when adjusting the shocks. Boarding the vehicle creates sudden shock compression, which can cause pinched fingers during maintenance.

The compression damping clicker knob is located at the top of the shock reservoir.

Turn the clicker clockwise to increase compression damping.
Turn the clicker counter-clockwise to decrease compression damping.


Location	Clicker Position
Front	8/16 clicks
Rear	8/16 clicks

Front / Rear Spring Preload Adjustment

Elevate the vehicle to allow the suspension to fully extend.
Turn the adjusting ring to the left to add preload. Turn the adjusting ring to the right to remove preload. If equipped, apply the locking ring when desired preload is adjusted.

WARNING

Uneven adjustment may cause poor handling of the vehicle, which could result in an accident. Always adjust both the left and right spring preloads equally or have your POLARIS dealer or qualified person perform the adjustments.
