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.
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. Installs in any new or undamaged used stock 2zz oil pump housing. Also available expertly assembled by MWR in a new Toyota OEM oil pump housing (see related items below.)
