The front rear scissor stop FRSS controls the bump attitude of the rear suspension As the front torque arm FTA hits the bump it forces the rear scissor to collapse a predetermined amount depending on the FRSS block position 8 53 9922854 2007 2011 IQ Service Manual 2010 Polaris Sales Inc Steering and Suspensions This accomplishes two important things First it allows a lighter spring rate on the FTA because it can borrow spring rate from the rear torsion springs Second it prepares the rear portion of the suspension for the bump reducing secondary kick back The FRSS is made of a resilient material allowing smooth action and preventing any suspension component damage The RRSS controls weight transfer from the rear suspension to the skis It also influences the stiffness of the ride by controlling the amount of coupling action between the front and rear torque arms To decrease weight transfer the RRSS should be set in the high position The RRSS can be removed for maximum weight transfer However unless the torsion springs and rear shock valving are changed the ride will be compromised Always maintain equal adjustment on both sides The dot is an indicator of the HIGH position The sides are the LOW position and the bottom is the MEDIUM position HIGH o MEDIUM LOW LOW Torsion Spring Adjustment To adjust the rear torsion spring r2. 8 53 ADJUSTMENT PROCEDURES 0 000 ccc cee eee eee eens 8 53 REAR SUSPENSION RIDE HEIGHT 8 53 SCISSOR STOP ADJUSTMENT 8 53 TORSION SPRING ADJUSTMENT 0 0000 cece eee eee eens 8 54 LIMITER STRAP ADJUSTMENT 0000 c cc eee eens 8 54 M 10 SUSPENSION 0 0 00 ee ee eee teens 8 55 RAIL SLIDERS t reete eaters aceti eite Ba bd 8 57 REAR SUSPENSION REMOVAL AND INSTALLATION 8 58 REMOVAL uo sas en eo ele eth ede ae a aa tod put hr oak 8 58 INSTALLATION bua a a es WA ee 8 58 POLARIS 9922854 2007 2011 IQ Service Manual 8 1 2010 Polaris Sales Inc Steering and Suspensions OVERVIEW SPECIFICATIONS Inspection When inspecting steering and suspension components for wear or damage always replace parts as necessary Refer to the assembly exploded views in this chapter for identification of components and torque values of fasteners Make notes of the direction a bolt goes through a part what type of nut is used in an application etc Some of the fasteners used in the IFS are special and cannot be purchased at a hardware store Always use genuine Polaris parts and hardware when replacing front end components Review steering adjustment guidelines before making adjustments The following components must be inspected at this time Tie rods and tie rod en
