Master Cylinder Aluminum Black .750 In. Bore

The Master Cylinder Aluminum Black .750 In. Bore by McLEOD is a precision-engineered clutch master cylinder designed for drivers who demand reliability and smooth engagement in performance and street applications. Built for manual transmission vehicles, this component serves as the hydraulic control point for your clutch system, converting pedal pressure into fluid pressure that actuates the slave cylinder. Whether you're upgrading from worn OEM equipment or building a modified drivetrain, a quality aluminum master cylinder is essential for consistent pedal feel and clutch modulation.

The .750-inch bore diameter is optimized for balanced pedal effort and fluid displacement, offering a proven diameter that works across a wide range of clutch setups without requiring excessive pedal travel. Constructed from lightweight aluminum with black anodized finish, this master cylinder resists corrosion while reducing unsprung weight compared to cast iron alternatives. The 1.12-inch stroke delivers adequate fluid volume for smooth, progressive clutch application, making it ideal for both daily drivers and weekend track cars. Black anodizing provides durability and a professional appearance while protecting the aluminum from oxidation in engine bay environments.

This master cylinder suits drivers installing new hydraulic clutch systems, upgrading aging factory equipment, or retrofitting modern controls into classic or custom builds. Verify mounting bolt pattern and brake/clutch line port thread compatibility with your vehicle's firewall configuration before ordering. Installation pairs well with matching slave cylinders and quality DOT 3 or DOT 4 brake fluid; proper bleeding is critical for air-free operation. The compact 5.65 x 3.3 x 13.35-inch envelope fits most underhood spaces, and at 1.12 lbs, it maintains your build's weight budget without sacrificing hydraulic integrity.
