With this in mind, PRP has produced a cost-effective way to fix this issue allowing you to keep your engine running longer while pushing it hard. Manufactured from EN26 Billet Steel, All gears are surface ground to perfection then isotropic polished to a near mirror finish.
These new gears are significantly stronger than the OEM gears as well as all other aftermarket gear and fit directly into your oil pump housing without modification.
