104680-45 Billet 4-5-6 Clutch Hub & Intermediate Shaft for GM 6L80 Transmission
When it comes to strengthening your GM 6L80 transmission for high-performance or heavy-duty applications, the 104680-45 Billet 4-5-6 Clutch Hub and Intermediate Shaft is the ultimate upgrade. This shaft assembly is forged from a single piece of premium 300M billet steel, renowned for its incredible strength and fatigue resistance. The one-piece design eliminates the OE shaft’s known weak point—a welded connection that is prone to failure under stress—ensuring maximum reliability during high torque or high RPM conditions.
The 104680-45 unit is heat-treated and shot-peened to further enhance its durability and resistance to cracking or fatigue. Engineered to accept 45-tooth clutch plates, this billet hub is specifically designed to optimize clutch engagement and heat management. It doubles oil flow to the clutch pack, which is crucial for protecting against heat buildup, especially when the 4-5-6 clutch pack is released in 1st, 2nd, and 3rd gears. The improved fluid dynamics reduce the risk of clutch failure and ensure longer life under demanding conditions like towing, racing, or spirited street driving.
Perfect for transmission builders, performance shops, and serious DIYers looking to upgrade their 6L80 transmission, this billet clutch hub and intermediate shaft combo delivers unmatched reliability, strength, and thermal efficiency. Whether you’re planning a high-horsepower street build or enhancing drivetrain durability for extreme use, the 104680-45 provides the protection and performance you need. Shop this vehicle upgrade today and experience the confidence that comes with top-tier engineering.
