Product Description
This kit includes:
- Spline Collar
- Inner Oil Pump Gear
- Outer Oil Pump Gear
Now with Isotropic Micro Finish!
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 Style oil pumps. Spline collar has to be fitted to the crank ( crank has to be removed from engine for fitment )
This type of setup is used in all OEM Toyota 1JZ and 2JZ oil pumps and numerous other OEM engines. There is no "chatter" or "back lash" which is common with the OEM RB drive setup.
