Zoo Performance N1 Type RB25/26 Billet Spline Driven Oil Pump Gears

RB SERIES 

These spline driven oil pump gears are manufactured from Billet 4340 steel and are made to suit N1, RB20, RB25 (non-neo) and early RB26 oil pumps.  These gears are designed with a special wave profile to ensure higher flow. 

Outer Gear Diameter: 77mm / Thickness: 10.96mm

They are heat-treated to make sure they'll last under the toughest performance conditions. These gears are drastically stronger than the standard gears which are prone to failure on modified vehicles.

Our gears have undergone harsh testing and are QC checked by our own team here in Australia,  tolerances are all within 0.02 thou and therefore we can guarantee the same tolerances in all the gears, no variants at all.

• Spline Collar

*We highly recommend speaking with your engine builder or tuner in regards to upgrading your oil pump spring.
