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.
