James Gaskets Transmission O-rings And Seals

34 products — part of all Transmission O-rings And Seals

James Gaskets transmission O-rings and seals cover Harley-Davidson gearboxes from the 1965 to early 1966 4-speed Big Twin through to 2026 Softail and FLT/Touring — taking in the 1982 to 1986 4-speed, the late 1981 to 1984 4-speed, the 1980 to 1990 5-speed Big Twin, the 1980 to early 1984 FLT/Touring and FXR, the 1991 to 1998 Dyna, and the current 2007 to 2026 Softail, Dyna, and FLT/Touring. Each generation of Harley-Davidson transmission uses different O-ring compounds and seal dimensions — the material that seats properly in a 1982 4-speed case doesn't behave the same way in a 2020 Milwaukee-Eight 6-speed under modern synthetic oil. James Gaskets has been calibrating this difference since 1979, exclusively for Harley-Davidson applications. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks the full James Gaskets transmission O-ring and seal range through Iron Stable.
