Product Details
The Honda OEM K-Series Countershaft Needle Bearing is a genuine factory replacement designed to provide smooth gear rotation, precise support, and dependable performance in compatible Honda and Acura manual transmissions.
Manufactured to Honda's original equipment specifications, this precision-engineered needle roller bearing measures 47mm x 52mm x 23mm and is designed for the countershaft first gear assembly in select K-Series manual transmissions.
Commonly used in vehicles such as the 2002–2006 Acura RSX, 2002–2005 Honda Civic Si, and select Honda Accord, CR-V, and Element manual transmission applications, this genuine Honda bearing is an excellent replacement for worn or damaged original transmission components.
Needle roller bearings use cylindrical rollers to provide rotational support within a compact space. This design is particularly useful inside manual transmissions, where gears must rotate smoothly while maintaining proper alignment under changing drivetrain loads.
Over time, needle bearings can develop wear from high mileage, contaminated transmission fluid, excessive drivetrain loads, or aggressive driving. A worn countershaft needle bearing may contribute to abnormal transmission noise, rough gear rotation, or accelerated wear of surrounding components.
Whether you're rebuilding an Acura RSX Type-S 6-speed transmission, refreshing a Civic Si gearbox, or preparing a K20/K24 drivetrain for a performance build, this genuine Honda OEM Countershaft Needle Bearing provides factory-correct dimensions and dependable construction.
