Wilwood 1-1/8" Bore Compact Tandem Master Cylinder, Black E-Coat (260-14960-BK)

Genuine Wilwood · Compact Design · 1-1/8" Bore · Black E-Coat · Tandem Outlet · Part # 260-14960-BK

Short on room under the hood? Wilwood's Compact Tandem Master Cylinder is about 1.6" shorter than their standard aluminum tandem master, at just 7.16" overall. It's machined from a high-pressure aluminum die casting and weighs only about 3 lbs, roughly 75% lighter than most cast iron OE-style master cylinders, with a glossy black E-coat finish.

The 1-1/8" bore is designed primarily for power brake systems, with vacuum or hydraulic assist. The mounting flange fits 3.22" to 3.40" bolt spacing, common on most domestic cars and trucks from the mid 1960s to today, and fluid outlet ports on both sides of the bore make plumbing easy.
