FOX ECS2 - External Reservoir Coolers

****This product is always in stock!! You must call to order this kit as it requires an installation on the shocks and can only be done in shop. Call 623-217-4959 to order your kit today!! There is additional labor to install the ECS2**** Born out of the FOX R.A.D. program, the ECS2 Cooler upgrade puts UTV race-dominating technology into a package that can benefit anyone who has a FOX-equipped sport UTV and a need for speed! Racing or riding at high speed for sustained durations heats the shocks significantly. As oil temperature climbs, viscosity decreases. Decreased viscosity means less damping force and less control. Extreme heat can push shocks past their ideal operating zone, resulting in shock fade. The ECS2 Cooler functions as a heat exchanger, reducing shock oil temperature so damping force stays more consistent. During development, test engineers observed more than a 70°F drop in shock operating temperature in both dyno and field tests. The cooling system can be added to most 2.5- or 3.0-inch diameter FOX UTV shocks and relies on a check valve to produce unidirectional oil flow. As the shock compresses, oil flows through the ECS2 Cooler and dumps into the reservoir. On the rebound, cooled oil flows back into the shock, maintaining optimal damping function. FEATURES Unidirectional oil flow Impact extruded 6063-T5 aluminum alloy Internal and external fins for maximum cooling surface area and heat dissipation BENEFITS Maintain consistent damping force Longer service intervals in extreme heat conditions Better performance for racing and riding at high speed for extended durations COMPATIBILITY Existing FOX UTV shocks only Most FOX 2.5” and 3.0” rear shocks Professional installation required by Shock Therapy in Phoenix, Arizona or the FOX Midwest Service Center in Baxter, Minnesota. Fitment options and pricing are based on your existing FOX shocks. //ridefox.com/ECS2  *The ECS2 system can only be purchased & installed through Shock Therapy*
