Wilwood High Volume Tandem Master Cylinder - 7/8in Bore Black-W/Pushrod

Wilwood's 7/8" or 15/16" bore Tandem Aluminum Master Cylinders are available in plain, ball burnished, and black e-coat finishes. These master cylinders are designed primarily for manual applications and include a pushrod. They are compatible with mount flanges from 3.22" to 3.40", common measurements for most domestic cars and trucks from the mid-1960s to present. They feature fluid outlet ports on both sides of the bore. The stroke is set at 1.10" with a 2:1 volume ratio between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3 lbs, representing a 75% weight savings over most cast iron OE type master cylinders. A combination proportioning valve kit (PN 260-13190 or 220-13189 for retrofit kit) is also available.
