Fits 1980's-up Big Twin Oil Tanks & Transmission

2007-up Big Twin Primary Cover

SS1/2"x20x1/2" Magnetic Drain Plug for Harley Davidson

This drain plug can be used for Harley Davidson engine and transmission plugs from approximately 1980's to present day models. 1999 low riders and all Sportsters don't have a drain plug because they have a tube to drain the oil.

Starting in 2007, this plug fits the engine, transmission and the primary chain case as well, so three are required to overhaul the whole bike.

The SS stands for super seal, a built-in O-ring with a 15-degree taper which allows you to replace the plug without using sealant or purchasing a new O-Ring.

I replaced all 3 plugs today. The stock magnetic plugs would not even support themselves when stuck to my tool chest. Wow. Didn’t realize they were that weak. Thanks for providing an American made product of such great quality. I feel better knowing my investment is protected now.
