THE PERFECT FIT
IQ Front Suspension Adjustments
Front 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.
A = Low preload
B = High preload
Increasing the spring preload too much
may adversely affect the handling of the
snowmobile and the performance of the
rear suspension.
Decreasing the spring preload too much
may allow the upper spring retainer to fall
off.
NOTE: Always leave at least one
thread showing above the nut.
1. Grasp the spring and turn it to the left to increase preload.
2. Turn the spring to the right to decrease preload.
Shock Damping (Walker/Evans Shock)
Turn the adjuster (1) clockwise to
increase stiffness. Turn the adjuster
counterclockwise to decrease stiffness.
