Front/Rear Arm Shock Compression
1. Turn the adjuster clockwise until it stops (hard
position).
2. Turn the adjuster counterclockwise to the initial setting
(see page 9 in this manual) or turn the adjuster counter-
clockwise the desired number of “clicks.”

NOTE: On the rear arm shock, the compression
adjuster has a total range of 18 “clicks” or 3 full
turns (6 “clicks” = 1 turn).
Front Arm Shock Spring
The skid frame front arm shock spring is adjustable.
However, Arctic Cat recommends that the shock
spring be adjusted to a maximum of 6.4 mm (1/4 in.)
up or down from the standard pre-load setting.

NOTE: The standard pre-load spring length (installed)
is 7.64 in.
When customizing the amount of ski pressure, be sure to
not over-adjust the front arm shock spring to adversely
affect steering and operator control of the snowmobile.
Some experimentation may be required until the proper
adjustment for the operator’s individual style is obtained.

NOTE: Each driver’s style is different and some
experimentation will be required to become famil-
iar with the above adjustment procedure.
Adjusting Rear Spring Tension
Rear spring tension adjustment is accomplished by rotat-
ing the adjusting cams. Position 3 provides the stiffest ride,
and position 1 provides the softest ride. Always rotate the
cam from the lighter position to the heavier position.
To rotate an adjusting cam, use a six-point box-end
wrench. Rotate the wrench until the cam is in the
desired position. To stiffen the ride, rotate the cam so
as to raise the spring end. Make the adjustment on the
other cam and be sure both cams are adjusted equally.
Servicing Zero-X Shock Absorbers
This procedure shows the proper method for servicing
the front arm shock absorber w/“piggy-back” reservoir.

NOTE: Some illustrations and photographs used
in the following sub-sections are used for clarity
purposes and are not designed to depict actual
conditions.
Disassembling
1. Remove the bearings and retaining rings from the
eyelets.
2. Clean the entire shock assembly with soapy water.
Dry the shock assembly with compressed air.

NOTE: If compressed air is not available, use
clean towel to dry the shock assembly.
3. Clamp the shock body eyelet securely in a soft-
jawed vise and remove the ball from the end cap;
then using a 3/16-in. hex key, slowly loosen the set
screw (FAV3 valve) on the shock reservoir.

CAUTION
Do not exceed the maximum 6.4 mm (1/4 in.) up or
down from the standard pre-load setting.
! WARNING
Do not adjust the front arm shock to a point at which
steering and operator control of the snowmobile are
adversely affected.
! WARNING
DO NOT make adjustments while operating the snow-
mobile. Keep both hands on the handlebar while the
snowmobile is moving.
CAUTION
Never force the adjustment cams from the low posi-
tion to the high position. Cam damage may occur.
! WARNING
Before starting, read through all of these instructions
first to become familiar with the procedure. Make sure
the work area is clean and all of the necessary tools
are available. These shocks contain high pressure
nitrogen gas. Always use proper safety equipment
such as latex gloves and safety glasses when working
on shock absorbers.
CAUTION
Use a soft-bristle brush to remove as much dirt and
debris as possible. Do not pressure wash the shock
as this can force water and debris inside causing dam-
age to the seals.
! WARNING
When using compressed air to dry components,
always wear safety glasses.
! WARNING
Always place a rag or towel over the valve and hex key
for protection when releasing the nitrogen from the
reservoir.
