Fox's gold-colored Kashima Coat.

For the best suspension yet, Fox has brought Miyaki Company of Japan’s legendary Kashima Coat to its shock bodies. You can recognize it by the unique gold color. This coating, which is four times harder than hard-anodized aluminum, made its name in car and motorcycle suspensions and drivetrains, and now you can enjoy all its amazing benefits. These include super low friction, excellent abrasion resistance and durability, and significantly better lubrication characteristics. In short, this shock is way more reactive, soaks up even tiny bumps and lasts longer with less maintenance, too.
