THE PERFECT FIT
Suspension Adjustments
Independent Front Suspension and Front Track Shock
Spring Preload
Factory settings, combined with user adjustments to the rear track shock
spring, should be all that’s necessary to provide the best riding
experience for most riders. The primary adjustment for overall vehicle
balance is torsion spring preload. Perform this adjustment first. See page
49.
After adjusting torsion spring preload, and if desired, additional
adjustments can be made to the independent front suspension and front
track shock preload.
When adjusting the front suspension, be sure the
springs on both sides of the vehicle are at the same adjustment. Always
perform shock spring preload adjustments with the weight of the vehicle
removed from the shock and with the shock at full extension.
For a softer ride on rough, washboard surfaces, reduce front track shock
(FTS) spring preload by 1-2 turns.
NOTICE: 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.
To improve corner stability, increase front suspension (IFS) spring
preload by 1-2 turns on both sides of the vehicle. Increasing the spring
preload too much may adversely affect the handling of the snowmobile
and the performance of the suspension. Never exceed one inch (2.54
cm) of preload beyond the factory settings.
