Designed for heavy-duty applications where space is limited, the Wilwood Compact Side Mount Master Cylinder offers a reliable and efficient hydraulic solution. Its ultra-short 3.37-inch body provides an extra 2.16 inches of clearance between the mounting boss and fluid outlet, making it ideal for tight engine bays or confined industrial settings. The integral side mounting lugs feature a 3.00-inch center-to-center distance, eliminating the need for a traditional mounting flange and allowing for flexible installation in restricted spaces. A full 1.12-inch piston stroke ensures compatibility with most full-size cylinders, delivering consistent braking performance under demanding conditions. The top-radius 1/8-inch NPT fluid outlet port minimizes air entrapment, promoting faster bleeding and more reliable operation. An enhanced fluid inlet port accommodates the standard reservoir included in the kit, while also supporting 11/16-20 internal threads for custom reservoir setups. The corrosion-resistant black E-Coated aluminum body maintains durability and long-lasting performance in harsh environments, making it suitable for automotive, industrial, or fleet applications requiring robust, space-efficient hydraulic control.
