Wilwoods Compact Combination Master Cylinders have been designed for limited space applications requiring the output capacity of a full size master cylinder. The ultra short 3.37compact body provides 2.16 of additional clearance between the mounting flange and the fluid outlet. A full 1.12 of piston stroke meets or exceeds the stroke capacity of most full size cylinders. With 18 NPT fluid outlet port located at the top radius of the cylinder bore, reduces the chances for trapped air. Enhanced fluid inlet port allows mounting of the standard reservoir included in kit and also contain 1116 - 20 internal threads for custom reservoir arrangements. The black E - Coated aluminum body resists corrosion and maintains a durable long lasting finish.
