Specially designed for the D5S and D5SGA, this limited production run carbon graphite motor fan mount adds little weight and looks fantastic in silver-red and silver-blue carbon weave pattern. Aluminium motor fans like the 3RAC-FAN10 or 3RAC-FAN11 are a sensible upgrade to have as they help to keep motor temperatures low to extend performance and longevity. Not compatible with the D5 Pro.
