Offroad Race Suspension Upgrades
"In a race like San Felipe we cycle the shocks so hard and fast that we build up a lot of temperature. The Cactus Cooler allows us to push harder and longer than our competitors." —Jesse Jones
External Cooling System (ECS)
The External Cooling System (ECS) is an option on all new and existing 3.0, 3.5, and 4.4 FOX bypass shocks. The ECS cooling system, code named "Cactus Cooler", during development, effectively drops fluid temperatures up to 150 degrees. Without pumps or fans, it uses the normal motion of the shock piston as it cycles up and down to pump the fluid through a billet aluminum and stainless steel heat sink.
$500
Includes the cooler itself, hoses, and the modifications to shock to accept the hoses that attach the cooler to the shock.
