33-4126 Pinion gear 54-77. White

This S&S pinion gear is the White color-coded variant, manufactured to the exacting standards required for vintage Big Twin engine builds. It fits 1954 to early 1977 Big Twin models and is a direct replacement for OEM 24010-54. For proper operation, this gear should be paired with a 1973 to 1999 style 24-tooth driven gear, equivalent to OEM 26345-73. S&S uses the same color-coding sequence as the factory to help mechanics achieve the correct gear lash. Proper fitment is essential; a gear that is too tight will cause binding, while one that is too loose will result in excessive engine noise. This White gear allows for precise adjustment when timing your bottom end.
