Front/Rear Spring Preload
The front and rear suspensions are preload adjustable. The suspensions are set to the factory preload as shown below. 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. Always heed the following rules if you make adjustments to this suspension.
-
Always return the suspension to the factory preload after the load is removed from the vehicle. The increased suspension height will negatively impact vehicle stability when operating without a load.
-
Always apply the same adjustment setting to all four wheels.
-
Do not increase the spring preload by more than one inch (25.4 mm) over the factory setting.

Your POLARIS dealer, or other qualified person, can provide the tool required to make suspension adjustments.
-
Elevate the vehicle to allow the suspension to fully extend.
-
Turn the preload nut to the left (1) to increase preload for a stiffer ride. Turn the preload nut to the right (2) to decrease preload for a softer ride.
WARNINGUneven adjustment may cause poor handling of the vehicle, which could result in an accident. Always adjust both the left and right spring preloads equally. Your POLARIS dealer, or other qualified person, can assist.
