Installation Guide


The REVSeries carbon fiber driveshaft is a direct bolt-in modification whose performance speaks for itself! It features the same high-quality materials and benefits as the rest of QA1's REV Series driveshafts. Additionally, this driveshaft is SFI-Certified! To learn more about SFI, please click here.


QA1's Mustang driveshafts feature Spicer Life Series 1350 U-joints and utilize a high-speed CV joint with a high-speed sealing boot and high temp grease. This high-speed capability allows us to minimize effects of NVH while increasing performance.
