THE PERFECT FIT

IQ Rear Suspension Adjustments

Suspension Coupling

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 up as one, allowing the

suspension to hit the bump only once and eliminating kickback.
The factory setting is usually adequate for all riders and conditions.
