Upgrade your vintage Ironhead’s charging system with this rare ACCEL Arlen Ness Signature Series voltage regulator.

  • Arlen Ness Signature Series: A rare, high-performance collaboration part from the "King of Choppers," combining ACCEL's electrical expertise with Ness's iconic styling.
  • Environmentally Sealed: Internal components are fully potted and sealed to protect against moisture, road grime, and extreme engine vibration.
  • Direct Bolt-On: Designed to mount in the factory location using your existing hardware for a clean, professional install.
