THE PERFECT FIT Shock Spring Preload Front Suspension Adjustments 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 front shock spring preload, grasp the spring and rotate it. Increasing the spring preload too much may adversely affect the handling of the snowmobile and the performance of the suspension. Never exceed one inch of preload beyond the factory settings, and ensure that both sides are adjusted the High Low same. When decreasing preload, make Preload Preload 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: Not all models have shocks with thread-adjustable spring preload. See your dealer for more information. NOTICE: On some models equipped with a plastic adjuster nut, the nut will break if it is unscrewed from the threaded body. Do not force the nut if resistance suddenly increases while you're turning it. 42
