Clutch springs for your Triumph motorcycle clutch basket / pressure plate. These are new old stock originals, so they might be a little dirty from sitting around for 40 years or so, but we figured that originals are better than new repops. You get a set of four clutch springs, pre unit Triumphs take four springs, or use three of these in your 500 / 650 / 750 c.c. Triumph or BSA A50 / A65 and keep the fourth as a spare. These are unit clutch springs, the stock pre unit ones are slightly lighter duty, however you can use these in your pre unit and it will just help keep a tighter clutch when engaged. The stock part number is 57-1830.
