Rear Master Cylinder Weld-On Adapter Mount

This rear master cylinder weld-on adapter mount is designed to convert early Harley-Davidson frames with the factory 2-bolt rear master cylinder mount to accept later-style OEM rear master cylinders.

Perfect for FXR builds, this mount allows seamless use of modern braking components when upgrading or swapping drivetrains, ideal for Twin Cam or Milwaukee-Eight (M8) swaps where later-model master cylinders are required.

Precision-cut from steel and formed for proper alignment, this bracket welds directly to the frame, providing a strong, clean solution without hacky spacers or guesswork. Built for custom builders who want OEM-style fitment with modern performance.

Features:

• Converts early 2-bolt rear master cylinder mounts to late-style master cylinders
• Weld-on design for strength and permanent installation
• Ideal for FXR (or other custom applications) chassis swapping to Twin Cam or M8, using OEM Master Cylinder
• Raw steel finish, ready for welding and final finishing
