THE PERFECT FIT
Rear Suspension Adjustments
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.
Adjustment
Locate the adjustment screw (A) 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 36). Return the screw
to its original starting position after the torsion spring has been
tightened.
A
Optional Coil Springs
Different rate coil springs are available for some shocks if a firmer ride
is desired. Contact your dealer for more information.
