TeraFlex High-Angle Rzeppa CV Driveshafts combine the smooth torque transfer of a CV joint with the high-angle misalignment of a traditional U-joint. This unique Rzeppa CV Joint and high-angle boot are designed for the extreme angles associated with larger lift heights. Laser welded 2-3/8" carbon steel tubing results in superior strength and longevity. Precision construction reduces harmonic vibration for smoother high RPM dynamics. These driveshafts are zeroed out during final assembly for a true centric assembly without need for balance weights. Unlike a U-joint style driveshaft the Rzeppa CV joint does not experience a significant loss in strength due to high angles. Our innovative features address all the shortcomings found in the factory style driveshaft without sacrificing the benefits. This is especially important on JK Wrangler/Unlimited models with 3"+ lift.
