One of the biggest problems with the Rb engine is the engagement between the crank collar and the oil pump gear. So we have come up with a design to fix this problem and to insure maximum engagement between the two.

Precision machined from 4340 billet steel, featuring an N1 spec ‘wave’ profile for higher flow.

Kit includes:

  • Spline collar
  • Inner gear
  • Outer gear

Please note: there is two different size oil pump gear's
