Wilwood 260-8555-P Aluminum Tandem Master Cylinder, 1" Bore, Chrome Powder Coat

Wilwood 1" Bore Aluminum Tandem Master Cylinder, Chrome Powder Coat (260-8555-P)

Genuine Wilwood · 1" Bore · Chrome Powder Coat · Tandem Outlet · Integral Reservoir · Part # 260-8555-P

Lose the heavy cast iron and step up to a genuine Wilwood. This tandem master cylinder is 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. The chrome powder coat finish gives it a clean, finished look under the hood.

The 1" bore works in both manual and power brake systems. 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.
