THE PERFECT FIT Shock Valving IQ Front Suspension Adjustments Some shocks can be revalved if spring preload alone isn't sufficient and further adjustment is desired to control suspension stiffness. Please see your Polaris dealer. WARNING Changing shock valving requires special tools and a sound knowledge of mechanical theory, tool use, and shop procedures to perform the work safely and correctly. Shocks contain high-pressure nitrogen gas. Use extreme caution when handling high-pressure service equipment. We recommend that this work be performed by a Polaris dealer. Front Springs IQ only: The front spring rates can be adjusted by changing the nitrogen pressure. The upper chamber adjusts the main spring rate. The lower chamber adjusts preload. See your Polaris dealer for more information. Switchback only: The front springs can be changed if spring preload alone isn't sufficient and further adjustment is desired to control suspension stiffness. Please see your Polaris dealer. 52
