Precision-Engineered Main Shafts for Maximum Torque

The main shaft is the backbone of your transmission, transferring power from the gearset to the drivetrain. The Coan Engineering 300M alloy main shaft is designed for those who refuse to compromise on strength. Featuring advanced rolled splines, this shaft offers superior fatigue resistance compared to traditional cut-spline designs, making it ideal for high-stress racing environments.

Why Choose 300M Alloy?

• Rolled Splines: Increases surface density and strength at the spline interface.
• 300M Steel: Offers superior tensile strength and impact resistance.
• Precision Machining: Ensures perfect alignment and minimal friction.
• Reliability: Engineered to handle extreme power levels in drag racing and street performance.

Whether you are building a championship-winning drag car or a high-performance street machine, the main shaft is a critical link in your power delivery system. Coan Engineering’s commitment to quality is evident in the meticulous heat treatment and finishing processes applied to this shaft. By reducing the risk of spline shear and shaft breakage, you can focus on your performance rather than worrying about drivetrain failure. Upgrade your transmission with the confidence that comes from using professional-grade components found at GGCRACING.
