Transmission Sprockets & Pulleys

This nut can be used when converting from thick spline pulley used on 1994-up Big Twins & 1995-up XL to the 93-older thin spline style sprocket or pulley.
This will make up for the extra spline length.
This is also necessary on 2006-Up Sportsters that do not have a removable seal adapter.

Made from High Carbon Steel

This cannot be used with our #3518 mainshaft spacer/seal adapter.
