Description

The Sonnax OE 6L80E Billet 456 intermediate shaft and hub is engineered as a robust solution to the common failure issues found in the original equipment shaft, particularly under high-horsepower, forced induction, or performance applications. This upgraded component eliminates the hub dampener and significantly increases the contact area between the hub and shaft by 300%, thereby enhancing durability and reliability. Constructed from high-strength 300M alloy steel, this intermediate shaft is heat-treated for maximum strength and longevity. It is designed as a 100% direct drop-in replacement, ensuring a straightforward installation process. The design also retains the locating groove for the OEM bearing, maintaining compatibility with existing components. This heavy-duty shaft is ideal for any GM 6L80 or 6L90 transmission experiencing high performance demands. It offers superior protection against shaft breakage and clutch failure, making it a critical upgrade for enthusiasts seeking to push their vehicles' capabilities.
