Designed for applications where space is limited, the Wilwood Compact Combination Master Cylinder offers the same output capacity as full-size cylinders while fitting into tight spaces. Its ultra-short 3.37-inch compact body provides an additional 2.16 inches of clearance between the mounting flange and the fluid outlet, making it ideal for custom automotive builds, heavy-duty equipment, and industrial machinery. The piston features a full 1.12-inch stroke, ensuring reliable brake or clutch operation that meets or exceeds the performance of larger cylinders. The top-radius 1/8-inch NPT fluid outlet port minimizes trapped air, promoting consistent and responsive fluid flow. An enhanced fluid inlet port accommodates a standard reservoir included in the kit, with internal 11/16-20 threads for adaptable reservoir configurations. The black E-Coated aluminum body resists corrosion, maintaining durability and a professional appearance in demanding environments. This master cylinder kit combines compact design with robust construction, making it suitable for a wide range of heavy-duty applications where space constraints are critical without compromising performance or reliability.
