Construction and Design:

• Forged from aluminum and then CNC machined into shape for exceptional strength and precision
• Coped cut out design follows the sculpted lines of Ness cartridge hubs & reduces weight
• Premium blue anodized finish for corrosion resistance and distinctive appearance
• Lightweight construction enhances performance while maintaining structural integrity

Compatibility and Specifications:

• Designed exclusively for Arlen Ness wheels with cartridge-type wheel hubs
• Accepts HD 24-up FLT front floating brake rotor hardware (factory & aftermarket)
• Compatible with 320mm diameter spoke-mounted floating front brake rotors
• Utilizes 5/16" diameter hub mount bolts for secure installation
• Accepts 2024-up 320mm floating rotor bolts found on touring models

When installed with a 320mm spoke mount rotor, this adapter creates a complete lightweight performance braking system. Sold individually. Note: This adapter is designed only for Arlen Ness wheels with cartridge type hubs; for stock or aftermarket circle hubs, use the Universal Ness Rotor Adapter series instead.
