THE PERFECT FIT<br />
Edge Rear Suspension Adjustments<br />
Suspension Coupling<br />
On all <strong>Polaris</strong> snowmobile rear suspensions, there are two torque arms<br />
that control the movement of the rail beam. Prior to the advent of<br />
suspension coupling, these torque arms could move independently of<br />
each other. Rear suspension coupling links the movement of the front<br />
and rear torque arms to each other. There are two types of rear<br />
suspension coupling.<br />
Front To Rear Coupling and the Front Rear<br />
Scissor Stop (FRSS)<br />
The front rear scissor stop (FRSS) couples the movement of the front<br />
torque arm with the rear torque arm and limits the amount of<br />
independence between the movement of the front torque arm and the<br />
rear torque arm.<br />
When hitting a bump, the front torque arm starts to compress. The<br />
FRSS links that movement to the rear torque arm, causing it to<br />
compress and raise the rear suspension up as one, allowing the<br />
suspension to hit the bump only once and eliminating kickback. Your<br />
FRSS is preset at the factory.<br />
