BSA 441 500 Single Clutch SPRING/NUT SET b44 b50 350

Last Tricor part numbers are 57-2748 for the nuts, 57-2727 for the springs.  All earlier BSA and Triumph numbers supersede to these.

Suitable for just about any BSA or Triumph single, nuts are made of stainless steel with HEX heads rather than the stock slotted affair, and MUCH easier to install.  Springs are of the heavier style made for 441 and 500.  This listing includes the complete set shown.
