SUSPENSION QUICK SET-UP GUIDE

WARNING

Suspension systems contain moving components that can crush or cut. Keep

hands clear of the suspension while the engine is running, someone is sitting

on the seat, or the suspension is in motion. NEVER adjust the suspension

while vehicle is in operation.

The front and rear suspensions on your MATRYX RMK snowmobile are easy to
adjust. Just remember three simple steps:

1. Ride your snowmobile.

2. Adjust the

rear track shock spring

to tune

vehicle balance

(ski pressure and

weight transfer).

3. Adjust

shock clickers

(if equipped) to tune

ride quality

(stiffer or softer ride).

Step 1: Ride your snowmobile.

Ride the snowmobile in various terrain to fully experience the existing
suspension settings before making any adjustments.

Step 2: Adjust the rear spring to tune vehicle balance.

After riding, you should be able to determine if the snowmobile needs more or
less transfer.

• For more transfer,

decrease

the rear track spring preload.

• For less transfer,

increase

the rear track spring preload.

For lighter steering, decrease the rear track spring preload or increase the front
track shock spring preload.

Step 3: Adjust shock clickers (if equipped) for ride quality.

For models equipped with monotube shocks, always adjust the rear track shock
spring preload to enhance bottoming resistance.

Walker Evans Racing® Velocity shocks come equipped with an inside clicker
(low-speed) and an outside clicker (high-speed). These clickers adjust shock
compression for high- and low-speed trail events. Adjust the clickers to control
bottoming and adjust ride comfort.

THE PERFECT FIT

• Turn clicker counter-clockwise to decrease damping for a softer ride.
• Turn clicker clockwise to increase damping for a stiffer ride and less

bottoming.

• Always adjust the low-speed adjustment control first. If desired ride is not

achieved, adjust the high-speed adjustment control to improve ride.

NOTICE

Always adjust the clicker at least one click below full stiff (full clockwise) or

shock damage will occur.

Test ride the snowmobile and continue making spring and clicker adjustments
until you achieve the perfect ride.

SHOCK COMPRESSION DAMPING

Shock compression damping is available for RMK KHAOS, and optional for
PRO-RMK.

The primary adjustment for overall vehicle balance is RTS spring preload.
Always perform the this adjustment first. After adjusting RTS spring preload to
your satisfaction, compression damping adjustments can be made to control
ride quality and bottoming resistance.

Compression damping can be adjusted on both the front and rear suspension.
Make adjustments in 2-click increments, then test ride. When adjusting the front
suspension, always adjust both clickers equally.

To stop bottoming

of the front or rear suspension (stiffer ride), rotate the clicker

(s) clockwise two clicks (as viewed from the top of the clicker), then test ride.
Repeat the adjustment until bottoming stops and the desired ride quality is
achieved.

For a more plush ride

at the front or rear suspension, rotate the clicker(s)

counter-clockwise two clicks, then test ride. Repeat the adjustment until the
desired ride quality is achieved.

INDEPENDENT FRONT SUSPENSION (IFS)

IFS SHOCK ADJUSTMENTS

Always perform shock spring preload adjustments with the weight of the vehicle
removed from the shock and with the shock at full extension.
