Driveshafts, Direct Fit REV Series Carbon Fiber, One-piece, Assembled, Balanced, 3.300 in. Diameter, SFI-approved, Rear, Ford, 4.6L, Each

Not all carbon fiber driveshafts are the same. QA1 has engineered their REV Series to be the ultimate in driveshaft technology. Unlike other carbon fiber models, QA1 REV performance driveshafts are designed and manufactured using the latest filament-winding equipment. They are specially wound with an exclusive 3M Matrix Resin that utilizes spherical nano scale silica, providing improved abrasion resistance and longevity, higher compressive strength, and minimal water absorption. They are fitted with precision CNC-machined forged yokes specially developed for QA1's 11-step bonding procedure and high-strength U-joints.

QA1 REV driveshafts will deliver abundant performance with less weight, maximum strength, lower inertia, faster acceleration, increased longevity, and the ability to handle much more torque. They are designed, manufactured and balanced to the highest standards and are intended for use in maximum performance applications where increased safety and vehicle performance are primary considerations. As a result of converting from an isolated 2-piece driveshaft design, it may be possible for an increase in NVH (noise, vibration, harshness) to occur in certain operating conditions.

Other notable features:
• Conversion u-joints available
• Harmonic-tested to ensure NVH requirements
• Precision-balanced to ensure smooth, vibration-free operation
• Torsion-tested and serialized
