Initial Shock Settings

Use the Initial Shock Settings Table below to set the 
vehicle suspension to the original factory configuration.

NOTE: A collumn for the RTS spring setting is not 
included as all vehicles require rider weight to set 
the spring length/SAG setting.  This information is 
located within this chapter.

Independent Front Suspension (IFS) Shock 

Settings

To change the IFS shock preload/installed spring height, 
raise the front of the snowmobile up and off the ground to 
remove the weight from the front suspension. Grasp the 
spring and rotate it. Increasing IFS shock spring preload 
too much may adversely affect the handling of the 
snowmobile and the performance of both the front and 
rear suspensions. Never exceed one inch (2.54 cm) of 
adjustment beyond the factory setting.

When decreasing IFS shock spring preload, make sure at 
least two turns of preload are holding the spring retainer 
against the spring. Failure to do so may cause the retainer 
to fall out when the shock is fully extended.

Adjusting the IFS shock spring preload raises or lowers 
the front vehicle ride height and either increases or 
decreases ski pressure when not accelerating. Increasing 
spring preload will also shift the vehicle balance towards 
the rear. Decreasing the spring preload will lower the front 
vehicle ride height and shift the vehicle balance towards 
the front.

The compression dampeners control ride comfort/quality. 
Turning the adjusters towards the SOFT setting (counter-
clockwise) will make the ride quality less harsh, but may 
cause the shocks to bottom out. Turning the adjuster 
towards the STIFF setting (clockwise) will make the ride 
quality stiffer.

Make equal adjustments to both shocks and only one to 
two clicks at a time. Heavier riders may want to set the 
compression clickers two to four clicks higher than lighter 
riders.

Rebound Adjustment

Rush 800 LE models feature IFS shocks with rebound 
adjusters.

The rebound adjustment clicker is located at the bottom of 
the shock rod. There are 16 possible settings. The initial 
factory setting is 8 clicks.

Make equal adjustments to both shocks and only one to 
two clicks at a time.

• Turning the clicker clockwise (inwards) increases 

rebound control and the shock will extend slower 
after being compressed.

• Turning the clicker counter-clockwise (outwards) 

decreased rebound control and the shock will 
extend faster after being compressed.

Front Track Shock (FTS) Factory Settings

To change the FTS spring preload, carefully tip the 
snowmobile onto its left side to remove weight from the 
front track shock. Grasp the spring and rotate it. 

When decreasing FTS spring preload, make sure at least 
two turns of preload are holding the spring retainer against 
the spring. Failure to do so may cause the retainer to fall 
out when the shock is fully extended.

When the snowmobile is not accelerating, Increasing FTS 
spring preload will decrease ski pressure. Decreasing 
FTS spring preload will increase ski pressure.

The compression dampener controls ride comfort/quality. 
Turning the adjuster towards the SOFT setting (counter-
clockwise) will make the ride quality less harsh, but may 
cause the FTS to bottom out. Turning the adjuster towards 
the STIFF setting (clockwise) will make the FTS stiffer.
