THE PERFECT FIT Front Suspension Adjustments IFS Shock Spring Preload Increasing spring preload will increase ski-to-ground pressure. Decreasing spring preload will decrease ski-to-ground pressure. When adjusting, be sure the springs on both the left and right sides of the machine are at the same adjustment. To change shock spring preload, grasp the spring retainer and rotate it. Initial IFS Preload Setting (from body end to spring) FOX shocks Ryde FX shocks 4.25" (10.8 cm) 5.25" (13.3 cm) Measure Increasing the spring preload too much may adversely affect the handling of the snowmobile and the performance of the suspension. Never exceed one inch (2.54 cm) of preload beyond the factory settings. NOTICE: When decreasing preload, make sure at least two turns of preload are holding the spring between the retainer on the top of the shock and the threaded spring preload adjuster nut on the shock body. Failure to do so could cause the retainer to fall off when the suspension is fully extended. TIP: Other spring options are available. Please see your POLARIS dealer. Low Preload High Preload Shock Valving 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. 46
