It is available in three finishes: plain, ball burnished, and black e-coat, providing options for corrosion resistance and aesthetic preference. The design includes fluid outlet ports on both sides of the bore, facilitating versatile plumbing configurations. Compatible with a range of vehicles, this master cylinder is engineered to deliver consistent, reliable braking performance, making it suitable for street and track use. Its robust construction ensures durability under demanding conditions, while the included pushrod simplifies installation.
This master cylinder is designed to fit mount flanges measuring from 3.22 inches to 3.40 inches, a common size for most domestic cars and trucks from the mid-1960s to the present. It is primarily intended for manual brake systems, serving as a direct replacement or upgrade for existing units. The product is well-suited for custom builds, restorations, or performance upgrades where precise brake modulation and reliability are essential. Installation involves bolting onto compatible mounting points, with fluid connections on both sides of the bore for flexible routing.

Wilwood's 7/8" or 15/16" bore Tandem Aluminum Master Cylinders available in 3 finishes, plain, ball burnished, and black e-coat. These master cylinders are designed primarily for manual applications and include 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 3lbs, a 75% weight savings over most cast iron OE type master cylinders. We also offer a combination proportioning valve kit, which includes brackets and stainless lines specifically for use with this master cylinder, see PN 260-13190, or 220-13189 for retrofit kit.
