Bare Knuckle Performance Overbearing For Harley Big Twin

Are you plagued by nighttime anxiety over the concentricity of your output shaft? Fear not, as Bare Knuckle Performance has the solution you so desperately need. The 1/2" Overbearing and 3/8" Overbearing 2.0 are designed to replace your factory mainshaft nut with a bearing-inclusive nut, drastically improving the concentricity of the shaft, reducing wear and minimizing leaks. Although Harley addressed this problem after 1964, this is your best bet for older models. The Overbearing 2.0 offers a lower profile option for custom applications and the standard Overbearing is your best bet for factory applications. Rest easy and do your bike a favor with a Bare Knuckle Performance Overbearing.

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
