Splined Rear Counterweight

Billet Inc.

  • $372.73


Rear Counterweight.  Suits all Billet Inc. splined eccentric shafts ONLY!  This is because the Billet Inc. eccentric shafts use a master-key in the splines to prevent incorrect assembly of eccentric lobes and rear counterweights.

These counterweights are CNC'ed billet xteel.  OEM counterweights are cast iron.

Always remember, you will need to have your rotating assembly balanced when changing any of the rotating components.  This includes rotors, counterweights and the eccentric shaft.  We offer a complete, precision balancing service for 12A, 13B, 20B and 26B engines.  Click here for more information.
