Wilwood's new Remote TandemMaster Cylinder w/ Pushrod is available in 4 bore sizes 7/8", 15/16", 1.00" and 1.12" and in two finishes: ball burnished and black e-coat. 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 1.12" 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 OEtype master cylinders. We alsooffer our combination proportioning valve kit, whichincludes brackets and stainless lines specifically for use with these master cylinders, see PN 260-14248 for a retrofit kit.
