Speedometer Block Off Plugs

4 products

Speedometer Block Off Plugs for Harley-Davidson give your transmission a clean, sealed finish when the mechanical speedo drive is no longer needed. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, our range includes trusted brands such as Jims and James Gaskets. These plugs are essential for 1996–2006 five-speed Big Twin and 1936–1984 four-speed Big Twin models that have been converted to electronic speedometers. If you ride a Softail, Dyna, or Touring machine and have removed the cable-driven speedo, a block off plug prevents oil leaks and keeps debris out of the transmission. Our full Harley-Davidson Instruments catalogue also covers speedo drives, mount kits, and covers for a complete instrument solution. Browse the full range below.
