Steering and Suspensions rear torsion springsSecond, it prepares the rear portion of the suspension for the bump, reducing secondary kick backThe FRSS is made of resilient material allowing smooth action and preventing any suspension component damageThe RRSS controls weight transfer from the rear suspension to the skisIt also influences the stiffness of the ride by controlling the amount of coupling action between the front and rear torque armsTo decrease weight transfer, the RRSS should be set in the high positionThe RRSS can be removed for maximum weight transferHowever, unless the torsion springs and rear shock valving are changed, the ride will be compromisedAlways maintain equal adjustment on both sidesThe dot is an indicator of the HIGH positionThe sides are the LOW position and the bottom is the MEDIUM position DEEP POWDER SNOW: Limiter strap in LOW position for maximum lift and flotation POWDER-HARDPACK: Limiter strap in STANDARD position for overall handling and speed over snow HARDPACK: Limiter strap in HIGH position for increased control and less transfer
