Precision cut from EN24 steel, Monkeywrench Racing’s 2ZZ oil pump gears have been thoroughly tested to take high heat, high rpm abuse without failure. This set of gears also features a Titanium Nitride (TiN) treatment which increases surface hardness and durability for extreme applications and an extra long service life. Expertly assembled by Monkeywrench Racing in a brand new OEM Toyota oil pump housing with relief valve.
The OEM Toyota/Lotus oil pump gears are made from sintered alloy- this is brittle and not strong enough. The OEM oil pump gears are known to fail frequently in high rpm racing applications and in the event of an accidental overrev.
Don’t risk your expensive engine’s safety!
