HDNB0004 Koyo needle bearing, transmission countershaft

When it comes to transmission bearings, you want a name you can trust for durability. This Koyo needle bearing, formerly produced by Torrington, is an open-end design built for the transmission countershaft. It fits a wide range of Harley models, including 1952 to 1956 K and KH models, 1957 through 1990 XL Sportsters, and late 1976 to 1986 4-speed Big Twins. It serves as a high-quality replacement for OEM 35961-52. Most of these gearboxes require two of these bearings for a complete service. Using a premium bearing like this from Sonnax ensures your countershaft has the support it needs to handle the torque of a V-twin without premature failure or excessive shaft play.
