These oil pump gears are machined from billet 4140 tool grade steel and are manufactured right here in Adelaide.
These gears are much stronger than the stock sintered steel gears that are provided with a stock motor and don’t stand up well with the added load of a forced induction upgrade.
When spending the money on building a performance engine this is one part you simply cannot afford to ignore.
Don’t be fooled by knock off gear sets for as much as $800+, buy HPDiesel and know your getting the best Australian made quality.
