Each unit is crafted with 3” ID x .155” wall carbon fiber tubing (3.31" OD), a 2024 aluminum bondable yoke and spline sleeve assembly, SONNAX 3 bolt adapter flange and NEAPCO 1350 Performance Series solid cross, non-greaseable U-joints.
Every driveshaft is high-speed balanced on our Coetz Balancer, and includes a printed balance verification sheet with your order. We also torque-test every carbon fiber assembly in-house, ensuring a secure bond and reliable performance under high-torque conditions. We’re proud to be one of only three U.S. shops performing in-house torque testing on every carbon fiber driveshaft we build.
