Spring Preload Adjustment (All Models)

All shocks installed on Timbersled snow bikes are equipped with spring preload adjusters. For factory spring settings, see the suspension setup section for your particular model.

CAUTION

DO NOT EXCEED the MIN / MAX preload values (defined by the tables in this section). Never adjust spring preload shorter than the minimum allowable length. Adjusting shorter than this length could result in damage to the suspension. Failure to comply may result in injury or damage to equipment.

ADJUSTING THE SUSPENSION

For those that wish to customize the ride quality of their snow bike, complete the following procedure:

  1. Ride your snow bike. Test ride your snow bike on preferred terrain to feel out the factory suspension settings prior to making any adjustments. Optimal suspension settings can change depending on terrain and skill level.

  2. Turn bike on side or elevate so shocks are fully extended.

    NOTICE
    Always perform shock spring preload adjustments with the weight of the vehicle removed from the shock and the shock is at full extension. Make spring preload adjustments in small increments (approximately 1/16th of an inch) and test ride quality between adjustments.

  3. Tune vehicle balance using rear shock preload adjuster. Adjusting the rear shock’s spring preload affects the smoothness of your ride by controlling the amount of weight transferred by the suspension. Increasing the preload will decrease the amount of weight transferred. Heavier riders will typically require more preload than lighter riders.

    TIP

    A spanner wrench is needed to adjust the preload on IFP and Walker Evans shocks. (Polaris P/N: 2871095-329)

    • For LESS weight transfer, increase the rear shock spring preload by turning the preload adjuster clockwise.

    • For MORE weight transfer, decrease the rear shock spring preload by turning the preload adjuster counterclockwise.

  4. Tune ski pressure. Manipulating the front shock spring preload in addition to the rear, will also adjust the snow bike’s ski-to-ground pressure. If the ski-to-ground pressure is too heavy or light, the bike may experience difficulties in steering and stability on certain terrain.

    • If ski-to-ground pressure is TOO HEAVY, increase the front shock spring preload and decrease the rear shock preload.

    • If ski-to-ground pressure is TOO LIGHT, decrease the front shock spring preload and increase the rear shock preload.
