THE PERFECT FIT
Rear Suspension Adjustments
Rear Shocks
Indy Select Rear Shock
Some snowmobiles are equipped with the Indy Select rear shock,
which allows for adjustments to the compression valving by turning
the adjustment screw located near the base of the shock.
Locate the adjustment screw (L) near the base of the shock. In
half-turn increments, turn the screw clockwise to increase compression
valving and stiffen the ride, or counterclockwise to reduce compression
and soften the ride. There are approximately three full turns of
adjustment available.
If bottoming continues after the screw has been turned fully clockwise,
the torsion spring should be adjusted (see page 43). Return the screw
to its original starting position after the torsion spring has been
adjusted.
