GM Forward Clutch Hub Billet Steel Alloy

The GM Forward Clutch Hub Billet Steel Alloy by COAN (SKU: COA22812) is a precision-engineered transmission component designed for builders and mechanics working with General Motors automatic transmissions seeking maximum durability and reliability. This forward clutch hub serves as a critical load-bearing element within the transmission's clutch pack assembly, transmitting torque from the turbine to the transmission's internal gears during forward acceleration. Whether you're rebuilding a stock transmission, upgrading a performance build, or restoring a classic GM vehicle, this billet steel hub replaces OEM components with superior material properties and tighter tolerances.

Manufactured from premium billet steel alloy rather than cast iron, the COAN forward clutch hub delivers exceptional strength-to-weight characteristics and resistance to thermal stress during sustained high-load operation. The billet construction eliminates casting porosity and weak points inherent in traditional cast hubs, providing superior fatigue resistance under repeated clutch engagement cycles—critical for drag racing, towing, or high-horsepower applications. At just 1.76 lbs with compact dimensions (4.8 x 2.7 x 5.5 inches), this hub maintains OEM geometry while offering enhanced material integrity, ensuring consistent clutch apply pressure and reduced slip-through during power delivery. The precision-machined surfaces guarantee proper fit within the transmission drum and optimal friction disc seating.

This forward clutch hub is ideal for transmission builders, performance shops, and serious DIY mechanics rebuilding GM TH400, TH350, or similar transmission platforms requiring OEM or upgraded components. COAN's billet hub is particularly valuable for high-horsepower applications where stock cast hubs may fracture under extreme torque or repeated engagement stress. Installation requires proper transmission disassembly and reassembly within the clutch drum cavity—a task best performed by experienced technicians or transmission specialists with appropriate tools and knowledge. Verify compatibility with your specific GM transmission model and clutch pack configuration before purchase to ensure correct fitment and performance.
