Steering and Suspensions This accomplishes two important thingsFirst, it allows lighter spring rate on the FTA because it can borrow spring rate from the 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 positionOne method of changing ski-to-snow pressure is to change the length of the front limiter straps Lengthening the straps decreases ski pressure under acceleration Shortening the straps increases ski pressure under accelerationSet up Recommendations for Optimum Performance (RMKSwitchback Rear Suspensions)
