Wilwood Chrysler-Style Tandem Master Cylinder, 1-1/16-inch Bore, Without Pushrod Kit

This Chrysler-style master supplies the tandem hydraulic cylinder and large plastic reservoir without the separate pushrod installation package. Its one-and-one-sixteenth-inch bore and two pressure outlets serve a properly designed drag, stock-car, street-rod or off-road brake system. Established in 1977 by Bill Wood, Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Calipers, fittings, rotors, valves, master cylinders and brake lines serve its motorsport, street-performance and specialized applications. The full assembly, including its mating connections and operating requirements, governs the correct part selection.
