24044-78 Pinion gear L77-89. Blue

For late 1977 to 1989 Big Twin engines, this JIMS blue pinion gear provides an average-sized fitment to help you achieve the perfect gear lash. Machined from top-tier American aerospace tool steel, JIMS gears are held to incredibly tight tolerances to prevent the common issues of valve train noise or premature wear. This specific gear is a reliable replacement for OEM 24044-78, though it is part of a color-coded range including numbers like 24040-78 through 24046-78. Getting the right size is essential for a quiet, efficient motor, and this blue gear is a staple for mechanics performing precision bottom-end work on Shovelhead and Evolution engines.
