Fox External Cooling System (ECS2) Cooler
Code-named “Shotgun Cooler” during development for its double barrel design, the External Cooling System (ECS2) has been torture-tested and race-proven to reduce shock fluid temperatures by up to 150ºF.
The ECS2 utilizes the shock’s rebound circuit to more effectively circulate shock fluid through the cooler and the shock. Dual aluminum chambers feature external and internal fins for increased cooling surface area, maximizing heat dissipation and its new, sleek design is 7.2 lbs lighter while delivering improved cooling efficiency over its predecessor.
The ECS2 is available in 3 lengths with standard -8 or -10 ports, the ECS2 can be installed on any FOX External Bypass shock. Its universal design also makes it an ideal cooler for transmissions, power steering and more.
