Description
Standard master cylinders often fall short when feeding large slave cylinders or running extended hydraulic lines. This Wilwood High-Volume clutch master cylinder solves that problem with the highest fluid capacity of any integral reservoir design -- 8.2 ounces total, at least 26% more fluid volume than other brands. That extra capacity means your clutch releases fully and consistently, even in demanding applications.
The high-pressure die-cast aluminum construction keeps weight down while standing up to the heat and pressure of high-performance driving. With 1-7/16" of piston travel, this master cylinder offers extra margin when paired with large piston slave cylinders, preventing the incomplete clutch release that plagues undersized units. Heavy-duty internal springs ensure fast piston retraction for a crisp pedal feel that snaps back without hesitation.
The 0.700" bore produces higher line pressure than larger bore units, making it well-suited for clutch actuation where pedal feel and full slave cylinder stroke matter more than raw volume displacement. The integral reservoir eliminates separate mounting and plumbing, simplifying installation in tight engine compartments. The formed steel lid with a bellows-type gasket keeps moisture contamination out of the system.
Wilwood uses common dimensions for both flange and side mounting with a standard 1/8-27 NPT outlet port, making this a direct upgrade for most hydraulic clutch setups. Ideal for performance street cars, road racing, and drag applications where reliable clutch actuation is critical.
