Wilwood High Volume Tandem Master Cylinder - 1 1/8in Bore Ball Burnished

Wilwood’s 1-1/8” bore Tandem Aluminum Master Cylinder with a chrome powder coat finish. It is designed primarily for use with power brake applications, either from vacuum assist or hydraulic assist systems. It is designed for mount flanges from 3.22” to 3.40”, which are common measurements for most domestic cars and trucks from the mid-1960s to present. It offers fluid outlet ports on both sides of the bore, a stroke of 1.10”, and a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, it weighs only 3lbs, offering a 75% weight savings over most cast iron OE type master cylinders. Wilwood also offers a combination proportioning valve kit (PN 260-13190, or 220-13189 for retrofit kit) specifically for use with these master cylinders.
