Bare Knuckle Performance Overbearing For Harley Big Twin

Do you wake up in the night with a cold sweat because you're worried about the concentricity of your output shaft? The Bare knuckle Performance Overbearing and Overbearing 2.0 are designed to replace your factory mainshaft nut with a nut that includes a bearing. This greatly increases the concentricity of the shaft, resulting in less wear and less leaks. Harley later fixed this issue after 1964. The Overbearing is prefect for stock configurations and the Overbearing 2.0 is made with a lower profile for custom applications. 

Features:

• Replaces mainshaft nut with a nut that includes a bearing
• Compatible with 4 speed transmission: Panhead, Knucklehead, Flathead
• Assure concentricity between your mainshaft and main drive gear
• Eliminates bushing wear, and therefore mainshaft leaks
• Choose from the original Overbearing, (for use with all OEM clutch and drive components), and Overbearing 2.0 (for use with aftermarket clutch and drive components)
• Made in USA
