IFS Shock Spring Preload (if equipped)

Increasing spring preload increases ski-to-ground pressure. Decreasing spring preload decreases ski-to-ground pressure. When adjusting, ensure the springs on both sides of the machine are set to the same length. To adjust shock spring preload, grasp the spring retainer and rotate it. Some models are not equipped with IFS spring adjuster. Please see your POLARIS dealer for accessory options.

Never exceed 1 in (2.54 cm) of preload beyond the factory settings. Over-extending the spring preload may adversely affect the handling of the snowmobile and the performance of the suspension.

When decreasing preload, ensure there are at least two full turns of preload holding the spring between the retainer on the top of the shock and the threaded spring preload adjuster nut on the shock body. Failure to do so could cause the retainer to fall off when the suspension is fully extended.
