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

This Wilwood High Volume Tandem Master Cylinder comes with a 7/8-inch bore and includes the necessary pushrod. It's machined from high-pressure die castings, making it a lightweight aluminum unit that weighs only 3lbs, offering a significant weight savings compared to heavier cast iron master cylinders. This unit is primarily intended for manual brake applications and features fluid outlet ports on both sides of the bore, giving you flexibility during installation.

Designed with mount flanges ranging from 3.22 inches to 3.40 inches, this master cylinder fits most domestic cars and trucks from the mid-1960s to the present day. The internal design includes a stroke set at 1.10 inches and a fluid volume ratio of 2:1 between the primary and secondary chambers, which helps ensure consistent braking performance. Its aluminum construction not only reduces weight but also contributes to its solid build.

For those looking to complete their brake system, Wilwood offers a combination proportioning valve kit (PN 260-13190 or 220-13189 for retrofit) that includes brackets and stainless lines specifically designed to work with this master cylinder.
