9090 45CI Transmission Main & Countershaft Roller Set, 40pc STD

This 40-piece standard roller set from Eastern MC Parts is a comprehensive solution for rebuilding the transmission on classic 45" and Servi-Car models. Designed to fit 1932 through 1974 transmissions, these rollers are used on both the mainshaft and countershaft to ensure smooth gear transitions and stable shaft alignment. Replacing worn rollers is a critical part of transmission maintenance to prevent gear whine and internal damage. These high-quality components replace OEM 9090 and are manufactured to withstand the stresses of vintage drivetrain operation. Sold as a set of 40, they provide everything you need to refresh the bearing surfaces in your classic Harley-Davidson gearbox for reliable shifting.
