QA1's One-Piece Carbon Fiber Driveshaft can withstand extreme racing environments, providing worry-free performance. The QA1-exclusive 3M Matrix Resin ensures ultimate torque capacity under the most extreme conditions. Utilizing a high-strength structural adhesive, this 11-step bonding procedure ensures a better balance and increased assembly strength. QA1's driveshafts have been subjected to various tests to meet SFI's 43.1 specifications for safety and performance.

QA1 Disclaimer: This product has been designed, manufactured and balanced to the highest standards and is intended for use in maximum performance applications where increased safety and vehicle performance are primary considerations. As a result of converting from an isolated two-piece driveshaft design, it may be possible for an increase in NVH (noise, vibration, harshness) to occur in certain operating conditions.

Additional Notes:
- Does not fit 2018+ EcoBoost, Shelby GT350 or GT500 Mustangs. This driveshaft will only fit 2018+ GT Mustangs equipped with an (10R80) automatic transmission.
- In the unlikely event of a failure, a carbon fiber driveshaft splinters, so racers don't have to worry about it coming up through the floor board and seriously hurting them or their car.
