McLeod Racing 34 bore master cylinders are made exclusively by Wilwood Engineering. The compact remote mount clutch master cylinders are precision - machined from high - strength aluminum. They have been designed for limited space applications requiring the output capacity of a full size master cylinder. They can be mounted directly onto the master cylinder, or remotely mounted for more convenient service access. A 8 hole flange bolts to a proprietary McLeod Billet aluminum mounting flange to provide easy installation in any vehicle.
