Suspension Coup lin g
On all Polaris snowmobile rear suspensions, there are two torque arms
that control the movement of the rail beam. Prior to the advent of
suspension coupling, these torque arms could move independently of
each other. Rear suspension coupling links the movement of the front
and rear torque arms to each other. There are two types of rear
suspension coupling.
Front To Rear Coupling and the Front Rear Scissor
Stop (FRSS)
The front rear scissor stop (FRSS) couples the movement of the front
torque arm with the rear torque arm and limits the amount of
independence between the movement of the front torque arm and the
rear torque arm.
When hitting a bump, the front torque arm starts to compress. The
FRSS links that movement to the rear torque arm, causing it to
compress and raise the rear suspension u p as one, allowing the
suspension to hit the bump only once and eliminating kickback. Your
FRSS is preset at the factory. Do not make any adjustments to the
position of the FRSS or your ride will be compromised.
