Transmission Seal Nut (Super Nut) for Harley-Davidson
18.15 €
Imported.
The Super Nut has enjoyed a solid reputation for decades.
Its added benefit? This mainshaft nut, with an integrated replaceable seal, will help keep transmission oil where it belongs: inside.
Note: Due to its increased height, it may interfere with the mainshaft support or internal primary cases. Note: See 518760 for the James replacement seal and 517165 for the replacement lockwasher.
Fits: 4-speed Big Twin >36-86
