Wilwood 260-18184 Aluminum Tandem Master Cylinder

Wilwood’s 15/16” bore Tandem Aluminum Master Cylinders available in 3 finishes, plain, chrome powder coat, and black e-coat. This bore can be used in manual and power assisted applications and does not come with a pushrod. They’re 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. We also offer a our combination proportioning valve kit, which includes brackets and stainless lines specifically for use with these master cylinders, see PN 260-13190, or 220-13189 for retrofit kit.
