Heat management is a secondary job of a shock. One way of improving the heat management is to add more oil. Larger-diameter shock bodies do this in some applications, and the remote-reservoir shock was invented to add significant oil capacity. The Bilstein 9300 Black Hawk uses a remote reservoir, and the shock body is made from 6061 extruded aluminum with a hard-anodized finish, which the company has found can reduce the operating temperature by up to 100 degrees in racing conditions. The shock also features incremental flow metering valve with nine settings for you to fine tune the valving.
