QA1 JJ-21223 REV Series Carbon Fiber Driveshaft One-Piece Manual Transmission

The QA1 JJ-21223 REV Series Carbon Fiber Driveshaft is a direct-fit, one-piece performance driveshaft engineered specifically for Mustang EcoBoost models equipped with a manual transmission. Wound in-house at QA1's Lakeville, Minnesota facility using advanced filament-winding equipment, this driveshaft delivers a significant upgrade over factory steel or two-piece aluminum units — offering reduced weight, increased strength, and improved power transfer.

Advanced Carbon Fiber Construction:

• Wound with an exclusive 3M Matrix Resin featuring spherical nano-scale silica for superior abrasion resistance, higher compressive strength, and minimal water absorption
• 3.3-inch diameter one-piece design replaces the factory two-piece driveshaft
• Lighter and stronger than steel, aluminum, and competing carbon fiber driveshafts
• Rated for up to 1,500 HP and 1,000 lb-ft of torque

Precision Engineered Hardware:

• Spicer Life Series 1350 U-joint on the transmission end for maximum durability
• High-speed CV joint on the differential end to minimize NVH at performance speeds
• High-speed sealing boot and high-temperature grease included
• Precision CNC-machined forged yokes developed for QA1's proprietary 11-step bonding procedure

Quality Assurance & Performance Benefits:

• Balanced as a complete assembly — no welded or bonded weights — for consistent, vibration-free operation
• Harmonic-tested to meet NVH requirements
• Torsion-tested and serialized for traceability
• Direct bolt-in installation — no drilling or modifications required
• Includes differential and transmission yokes/flanges
• Backed by a limited lifetime warranty

The QA1 REV Series carbon fiber driveshaft is the ideal upgrade for performance enthusiasts looking to reduce drivetrain rotational mass, improve acceleration, and extend the service life of their transmission and differential — all without sacrificing streetability.
