THE PERFECT FIT
Front Suspension Adjustments
Indy Select IFS Shock
Some snowmobiles are equipped with Indy Select IFS shocks, which
allow you to make adjustments to the compression valving of the front
shocks by turning adjustment screws (A) located near the base of the
shocks.
By turning the screw clockwise, the compression of the shock
increases, stiffening the ride. By turning counterclockwise, the
compression decreases, softening the ride.
The factory setting is in the softest position (screw all the way out -
counterclockwise). If bottoming occurs, the Indy Select feature should
be used to achieve the desired ride effect. One-half turn will affect the
ride considerably. There are about three turns of adjustment available.
If experimenting with this adjustment feature, turn the screw only 1/4
turn at a time. And always adjust both shocks equally.
