Description
These gears are a direct fit and replace the standard gears which are prone to failure when engine rpm is raised or the rev limiter is engaged which shock loads the gears enormously.
The factory gears are sintered (powdered metal compressed under extreme pressure and heat) and were never designed for high horsepower or high RPM applications.
Precision machined in Australia from 4340 billet steel and finished with an isotropic polishing process these gears deliver a stress-free, smooth running oil pump.
Tested and proven under extremely harsh conditions and used in many 1000kw barra engines.
Billet oil pump gears greatly reduce the chances of oil pump failure, which when fail, can cause massive amounts of damage very quickly to pistons, valves and camshafts.
Do not compromise your engine reliability by using inferior poorly manufactured gears and choose our precision machined gears for years of trouble free use.
