Front Track Shock Settings

Factory settings, combined with user adjustments to the rear track shock spring (RTSS), should be all that’s necessary to provide the best riding experience for most riders. The primary adjustment for overall vehicle balance is RTSS preload. Perform this adjustment first.

Always perform shock spring preload adjustments with the weight of the vehicle removed from the shock, limiter strap(s) disconnected, and the shock at full extension.

NOTICE

Never adjust spring preload to an installed length longer than the factory length or shorter than the minimum length as shown in the following chart. Damage to the suspension could result. When decreasing preload, make sure at least two turns of preload are holding the retainer against the spring.

The front track shock is measured from the bottom of the spring to the top of the body cap.
