Torsion Spring Tension

To adjust rear torsion spring tension, rotate the three-position cam using 

the engine spark plug tool. Adjustment is easiest when the cam is 

rotated from low to medium, and then to high. Rotating directly from 

low to high will require significantly more effort.

Different rate torsion springs are available if a firmer ride is desired.  

See 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 sus-

pension 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 indepen-

dence 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 reducing kickback. 

The factory setting is usually adequate for all riders and conditions.

Rear To Front Coupling and the Rear Rear Scissor Stop 

(RRSS)

The rear rear scissor stop (RRSS) couples the movement of the rear 

torque arm with the front torque arm and limits the amount of indepen-

dent movement between the rear torque and the front torque arm.

Adjusting the RRSS either allows more weight to transfer to the rear for 

more traction, or allows less weight to transfer to the rear, resulting in 

improved cornering performance. An adjustment dot is located on the 

RRSS. This dot is on the longest end of the scissor stop. 

Rear Rear Scissor Stop (RRSS) - Attributes

Moving the RRSS to a higher position will have the following effects on 

the suspension:
• Reduced weight transfer. 
• Improved chatter bump ride. 
• Improved cornering performance.

Weight Transfer During Acceleration

The preferred method for controlling 

weight transfer during acceleration is 

by adjusting the rear rear scissor stop 

(RRSS). The factory setting is the 

best for most trail riding conditions.

To decrease weight transfer under 

acceleration (for improved corner-

ing), rotate the RRSS to a higher 

position with the scissor stop tool 

located in your tool kit.

To increase weight transfer or ski lift 

during acceleration, rotate the RRSS 

to a lower position. 

NOTE: Your dealer can help you 

with initial setup and addi-

tional setup instructions to 

help you achieve your opti-

mum ride.
