C/F Driveshaft 3-1/4in Dia 37-1/2in Long

The Wiles Racing Carbon Fiber Driveshaft 3-1/4 inch diameter, 37-1/2 inch long is designed for performance enthusiasts and drag racers seeking lightweight power transfer without compromise. This 11-pound assembly replaces heavier stock driveshafts, reducing rotational mass and improving acceleration while maintaining the necessary structural rigidity for high-horsepower applications.

Constructed from carbon fiber, this driveshaft offers a superior strength-to-weight ratio compared to steel or aluminum alternatives, allowing for a weight reduction of approximately 8–12 pounds versus traditional driveshafts while increasing torsional stiffness. The 3-1/4 inch diameter profile is engineered to handle high-power drivetrain loads, resisting deflection under hard acceleration and sustained g-force cornering.

Ideal for mid-size to large American muscle cars, street rods, and custom hot rods, this 37-1/2 inch driveshaft fits where frame-to-axle geometry requires a standard-length solution. Wiles Racing's manufacturing process ensures balanced, concentricity-tested components that eliminate vibration and premature bearing wear, making it a reliable choice for optimized transmissions and rear differentials.
