THE PERFECT FIT
Edge 136 Rear Suspension Adjustments
(Indy 340 Touring)
Optional Coil Springs
Different rate coil springs are available for some shocks if a firmer ride
is desired. Contact your dealer for more information.
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. Your
FRSS is preset at the factory.
