Product details
This Wilwood adapter installs a dual-master-cylinder balance-bar arrangement at a compatible horizontal tandem-master mounting flange. Its oval attachment holes accommodate 3.22-3.40-inch centers, while the two master cylinders attach on 2.25-inch vertical centers. This component comes from Wilwood Engineering, the disc brake manufacturer established by Bill Wood in 1977 and based in Camarillo, California. Its design and manufacturing range includes calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications. Selection depends on the requirements of the complete brake system.

Fitment & Compatibility
For a custom brake-system conversion, not a replacement tandem master cylinder. Confirm firewall support, pushrod alignment, cylinder clearance, and hydraulic sizing. Master cylinders must be selected separately; this version is not the eyelet-equipped assembly.
Bring your assembly information to PMB Performance for help confirming this selection. More than 20 years of experience informs our approach to matching parts to the installation.
