Review MELLING Stock Replacement Gear And Shaft

The Melling G39B G-39B gear shaft is a high-performance component designed for use in racing and high-performance applications. This gear shaft is engineered to provide superior strength and durability compared to original equipment manufacturer (OEM) components, ensuring reliable operation under extreme conditions.

The Melling G39B G-39B gear shaft is machined from billet aluminum, ensuring a precise fit and exceptional strength. It features a hard anodized finish, which not only provides a durable protective coating but also reduces friction and wear. This gear shaft is designed to fit directly into the factory location on applicable engines, making it an easy and direct replacement for OEM components.

This gear shaft is also engineered with a proprietary Quad Ring design, which provides enhanced oil control and pressure distribution. The Quad Ring design features four oil control rings that provide positive sealing and oil control, ensuring that oil is properly directed to the various components of the engine. This not only helps to improve engine performance but also increases the lifespan of the engine by reducing wear and tear.

The Melling G39B G-39B gear shaft is also designed with a larger diameter than OEM components, which provides increased oil flow and improved cooling capabilities. This is especially important in high-performance applications where the engine operates at higher temperatures and requires more oil to maintain optimal performance.

In summary, the Melling G39B G-39B gear shaft is a high-performance component designed for use in racing and high-performance applications. It is machined from billet aluminum, features a hard anodized finish, and is engineered with a Quad Ring design for superior oil control and pressure distribution. Its larger diameter provides increased oil flow and improved cooling capabilities, making it a reliable and effective upgrade for OEM components.
