Lock Tabs for Engine Components

A lock tab is a thin metal tab that sits under a bolt head. Once the bolt is tightened, an edge of the tab is bent up against a flat on the bolt so it cannot turn and work loose. Engine vibration can slowly back fasteners out over time. Lock tabs are a simple, proven way to keep covers and other parts held tight. Many riders replace them whenever a cover comes off, since a tab that has been bent and flattened again may not hold as well.

We currently have 1 lock tab product in stock, from Bikers Choice. It is the Bikers Choice 87-99 Big Twin Inner Primary Cover Lock Tabs. It is listed as a replacement for H-D 33318-85 and sold as a 10 Pk. It is intended for Harley-Davidson Big Twin models.

  • Confirm that the year range and engine family match your bike.
  • Check the part number your service manual calls for.
  • Plan to fit new tabs whenever you remove the cover.
  • Inspect bolt threads and seating surfaces while the cover is off.
