After tons of requests from our customers we have finally came out with a extruded aluminum finned reservoir. The revolutionary FOA design is that ours is an extruded aluminum sleeve that will install on any existing FOA 2.5 reservoir shock. As well as many of our competitors reservoirs as well without dis assembling the shock. Real world testing shows on the rear of a class 2000 Ranger we have seen shock temps drop nearly 100 degrees.
