Indy Select Rear Shock

Some snowmobiles are equipped with the Indy Select rear shock, which 

allows for adjustments to the compression valving. Locate the adjust-

ment screw near the base of the shock. In half-turn increments, turn the 

screw clockwise to increase compression valving and stiffen the ride, or 

counterclockwise to reduce compression and soften the ride. There are 

approximately three full turns of adjustment available. 

If bottoming continues after the screw has been turned fully clockwise, 

the torsion spring should be adjusted (see page 35). Return the screw to 

its original starting position after the torsion spring has been tightened.

Optional Torsion Springs

Different rate torsion 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 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. 

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 condi-

tions.

To decrease weight transfer under 

acceleration (for improved corner-

ing), rotate the RRSS to a higher 

position.

To increase weight transfer or ski lift 

during acceleration, move the RRSS 

to the rearward hole on high posi-

tion. The RRSS may also be rotated 

to a lower position for even more 

weight transfer if desired.

Stock Position - This setting is most 

desirable for trail riding.

Medium or High Position (standard 

hole location) - This setting will 

decrease weight transfer.

Rearward Upper Position 

(optional hole location - This setting 

will increase weight transfer.

NOTE: Your dealer can help you with initial setup and additional setup 

instructions to help you achieve your optimum ride. A scissor 

stop tool is also available from your dealer.
