Rb Billet Oil Pump Gear
NISSAN RB BILLET 4340 OIL PUMP GEARS
These gears are direct replacement for STD and N1 oil pumps.
This set replaces the standard gears which are prone to failure even on light modification. The factory gears are sintered (powdered metal compressed under extreme pressure and heat) and were never designed for high horsepower or high RPM applications.
Precision machined from 4340 billet steel, featuring an N1 spec ‘wave’ profile for higher flow, JR'S gears have been repeatedly proven under extremely harsh conditions. All JR'S oil pump gears now go through isotropic polishing for stress-free, smooth running.
To-date, we have manufactured thousands of oil pump gears, many of them being installed in 1000+ horsepower vehicles.
Billet oil pump gears greatly reduce the chances of oil pump failure, which when fail, can cause massive amounts of damage very quickly to bearings, pistons, valves and camshafts.
There are two different oil pump options for Rb engines so please check sizing before placing orders.
