33-4124 Pinion gear 54-77. Blue

Getting the gear lash just right in a Panhead or Shovelhead motor is critical for a quiet and long-lasting engine. This S&S blue-coded pinion gear is an average-sized option designed for 1954 to early 1977 Big Twin models. It is engineered to work perfectly with the 1973 to 1999 style 24-tooth driven gear, corresponding to OEM 26345-73 and 24010-54. S&S follows the original Harley-Davidson color-coding sequence to make selection easier. Since zero gear lash causes binding and excessive lash creates noise, this blue gear offers a reliable middle-ground fitment for most builds. If you are unsure of the exact tolerance needed, starting with a gear from the middle of the range like this one is a standard mechanic's practice to ensure adequate clearance.
