A massive billet steel bell, hardened metal inner race, and a six-ball bearing cage are the core internals of the RCV CV-joint. While it may look like other CV-joints, it’s not. To compare the company’s CV ’shaft to a stock ’shaft, RCV used an axle testing jig and tested both at a 40-degree angle. At 3,872 lb-ft, the U-jointed ’shaft failed. By comparison, the axleshaft itself, not the CV, snapped on the RCV at 7,604 lb-ft. Did we mention RCV has a “you break it, we replace it warranty”?
