Wilwood 260-13616 Compact Remote Side Mount Master Cylinder 7/8in. Bore with Banjo Outlet

The Wilwood 260-13616 is a Compact Remote Side Mount Master Cylinder precision-machined from a high-pressure die-cast premium aluminum alloy. Engineered for performance street, racing, and custom builds where under-hood or chassis space is at a premium, this master cylinder delivers the full output capacity of a traditional full-size unit in a dramatically smaller package.

The ultra-short 3.37-inch compact body provides 2.16 inches of additional clearance between the mounting boss and the fluid outlet — a critical advantage in tight engine bays and custom fabrications. Unlike flange-mount designs, this unit features integral side mounting lugs on a 3.00-inch center-to-center spacing with no traditional mounting flange, further maximizing its ability to fit in confined spaces.

The 260-13616 is suited for club sport racers, open-wheel builds, street rods, off-road vehicles, and any custom application where space is limited. The kit includes both a standard direct-mount reservoir and provisions for remote reservoir installation, making it one of the most versatile compact master cylinders in the Wilwood lineup.
