It is well known that the factory powder metal 5.0L oil pump gears are weak and prone to failure on high horsepower applications. A broken gear set will cause your engine to lose oil pressure ultimately leading in catastrophic failure. Don't let this happen to your truck and upgrade the gears before they fail. JDM Engineering uses the Triangle Speed Shop billet crankshaft gears for all engine builds and high power applications.
Upgrade to the BOUNDARY Billet crank gear as well to make a bullet proof set!
