Wilwood Tandem M/C Aluminum 15/16in Bore - Chrome P-Coat

Wilwood’s 15/16” bore Tandem Aluminum Master Cylinders are available in plain, chrome powder coat, and black e-coat finishes. This bore can be used in manual and power-assisted applications and does not come with a pushrod. They are designed for mount flanges from 3.22” to 3.40”, common measurements for most domestic cars and trucks from the mid-1960s to present, and offer fluid outlet ports on both sides of the bore. The stroke is set at 1.10” with a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3 lbs, a 75% weight savings over most cast iron OE type master cylinders. Wilwood also offers a combination proportioning valve kit, which includes brackets and stainless lines specifically for use with these master cylinders (PN 260-13190, or 220-13189 for retrofit kit).
