Fox 986-02-023 Fox 2.0 Factory Series Smooth Body Emulsion Shock

These Fox Racing 2.0 Factory Series 6.5" Travel Shocks include an internal reservoir. A shock absorber that builds up too much heat will not function properly. As the shock absorber is exposed to exessive heat it will fade and/or fail. If you are experiencing excessive shock failure or fading, it may be time to step up to the performance of a Fox 2.0 Factory Series Shock Absorber, or possibly add another shock. By adding another shock, you are spreading the work load from one shock to multiple shocks. Increased cooling capability will be achieved from the following factors:Decreased Friction: When you use a multiple shock set up, lighter valved shocks can be used which will decrease friction.Increased Oil Capacity: The more oil, the better. Higher oil volumes take longer to heat. Another method of increasing oil capacity is to utilize a remote reservoir or use a larger diameter shock. The additional volume of the reservoir allows the Fox 2.0 shock to maintain a lower and more even operating temperature which allows them to survive under conditions that blow other shocks apart!
