Rear Shocks

Indy Select Rear Shock
Your snowmobile is equipped with the Indy Select rear shock, which 

allows for adjustments to the compression valving. 
1. Locate the adjustment screw near the base of the shock.
2. Adjust the screw 1/2 turn clockwise to increase compression valv-

ing and stiffen the ride. Test ride the snowmobile before making 

further adjustments.

NOTE: An excessive adjustment can result in damage to the shock. 

When adjusting these shocks, we recommend that you turn the 

screw only 1/2 turn at a time, then test ride. 

3. Adjust the screw 1/2 turn counterclockwise to reduce compression 

and soften the ride. 

There are approximately three full turns of adjustment available. If bot-

toming 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.

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 cornering), 

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, move the RRSS 

to the rearward hole on high position. 

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. The scissor 

stop is oriented with the mark posi-

tioned downward. 

Medium or High Position (standard 

hole location) - This setting will 

decrease weight transfer. The mark is 

positioned toward the torque arm.

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.
