Part No.: JJ-21208 | Available at Drag Racing Wheels
Upgrade your 2015–2018 Ford Mustang GT350 with the QA1 REV Series 3.3-inch Carbon Fiber Driveshaft, a high-performance, SFI-certified component engineered to enhance acceleration, reduce rotational mass, and improve drivetrain efficiency. Built with advanced carbon fiber construction and race-proven durability, this driveshaft is designed for track and high-performance street applications.
Lightweight Carbon Fiber for Maximum Performance
The QA1 REV Series Carbon Fiber Driveshaft is constructed using 3M Matrix Resin technology, making it lighter and stronger than steel, aluminum, and many other carbon fiber alternatives.
✔ Reduces rotational mass for quicker acceleration and sharper throttle response
✔ Delivers more power to the wheels by minimizing drivetrain loss
✔ Stronger and safer than traditional steel or aluminum driveshafts
✔ Eliminates flex and vibration issues found in stock two-piece driveshafts
By significantly reducing weight and improving balance, this high-performance driveshaft ensures maximum power transfer and a smoother ride under all conditions.
Precision-Engineered for Maximum Drivetrain Efficiency
Designed as a complete system, the QA1 driveshaft provides a seamless connection between the transmission and rear differential, eliminating the weaknesses of the factory two-piece design.
✔ Spicer Life Series 1350 U-joint on one end for extreme durability
✔ High-speed CV joint on the other end for smooth operation and reduced NVH (Noise, Vibration & Harshness)
✔ High-speed sealing boot and high-temp grease for long-term durability
✔ Balanced as a full assembly—no welded or bonded weights for superior precision
By eliminating the factory two-piece driveshaft, this one-piece carbon fiber upgrade offers better stability, reduced drivetrain flex, and enhanced power delivery.
Faster Acceleration & More Power to the Ground
By minimizing drivetrain loss and reducing weight, the QA1 Carbon Fiber Driveshaft allows for:
✔ Quicker acceleration and improved torque transfer
✔ Less rotational inertia for immediate throttle response

✔ Reducing drivetrain stress and shock loads on the transmission and differential
✔ Minimizing vibrations for smoother and quieter operation
✔ Providing enhanced durability under high-performance conditions
By reducing excessive movement and flex, this upgrade ensures longer-lasting drivetrain components, making it an ideal choice for track-focused GT350 builds.
