Shock Spring Preload
Increasing spring preload will increase ski-to-ground pressure. Decreasing spring preload will decrease ski-to-ground pressure. When adjusting, be sure the springs on both the left and right sides of the machine are at the same adjustment.
To change front shock spring preload, loosen the allen bolt in the spring nut 1. Grasp the spring nut and rotate it. Torque the allen bolt to specification.
TORQUE
Increasing the spring preload too much may adversely
affect the handling of the snowmobile and the performance of the suspension.
Never exceed a half inch (.500") of preload beyond the factory settings,
and ensure that both sides are adjusted the same. When decreasing
preload, make sure at least two turns of preload are 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.

TIP
Not all models have shocks with thread-adjustable
spring preload. See your dealer for more information.
NOTICE
On some models equipped with a plastic adjuster
nut, the nut will break if it is unscrewed from the threaded body.
Do not force the nut if resistance suddenly increases while you’re
turning it.
