Front / Rear Spring Preload Adjustment (Trail Boss Models Only)

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.

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.

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.

Model Location Factory Preload Measurement

Follow these guidelines if you make adjustments to this suspension.

  • Always return the suspension to the factory setting 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.
