Precision cut from 4340 steel, Monkeywrench Racing’s 2ZZ oil pump gears have been thoroughly tested to take high heat, high rpm abuse without failure. Standard uncoated version works great for most applications and has excellent durability.
Also available expertly assembled by MWR in a new Toyota OEM oil pump housing
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. Don’t risk your expensive engine’s safety!
