Brand: Optimum Balance Products (OBP)
The FC series compact master cylinders from obp Motorsport are the smallest we carry, measuring just 2 3/8" long! The mounting flange has the standard 2- bolt (5/16" holes, 2 1/4" center-to-center) but the flange is rotated 60 degrees for a more compact installation. Perfect for pedal boxes with angled mounting holes.
Despite the ultra-compact size, this 3/4" bore master cylinder retains an impressive 1.04" (26.5mm) stroke, displacing up to 7.54ml (0.46 CI) of fluid with a full stroke. The 7/16-20 inlet port allows remote-mount or direct-mount reservoirs, and the standard 3/8-24 outlet port and 5/16-24 pushrod thread make these a direct replacement for conventional single-outlet master cylinders from Girling, AP/Lockheed, and many more. Sold individually.
