These billet oil pump gears are manufactured from Billet 4340 steel and 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.
These gears have been scrutinised and QC checked by our own team here in Australia, tolerances are all within 0.2 thou and therefore we can guarantee the same tolerances in all the gears, no variants at all - guaranteed!
Our rear backing plate is also precision machined from 4340 billet steel which exceeds both strength and performance then your average 6061 backing plates.
*We highly recommend speaking with your engine builder or tuner in regards to upgrading your oil pump spring.
