RB OIL PUMP SPLINED GEAR SET (SPOOL IMPORTS)
RB Billet Spline Driven Oil Pump Gears to suit RB Nissan engines with 77mm ie; N1 Nissan.
This set replaces the standard N1, RB25 NEO and OEM GTR gears which are powdered metal.
Precision machined from 4340 billet steel, featuring an N1 spec 'wave' profile for higher flow. These gears have been proven under extremely harsh conditions & stress.
Spline driven gears are a much better, positive drive and more effective way to drive the Nissan oil pump.
This type of setup is used in all OEM Toyota 1JZ and 2JZ oil pumps ( See pics below ) and numerous other OEM engines. There is no "chatter" or "back lash" which is common with the OEM RB drive setup.
