Rubicon Express® RE1898-335 - Rear CVF Driveshaft

Traditional OEM drive shafts are built to run at straight or near-straight angles when transmitting power to the wheels. However, when a lift kit is installed, the wheels and the vehicle frame are pushed further apart. Because the operating angle of the joints which connect transfer cases to differentials becomes more severe as a result, standard universal joints can bind and become difficult to turn. Heat and pressure they were not designed to handle builds up - causing joint failure and breakage. Rubicon Express remedies this common problem effectively through their line of Universal Constant Velocity style drive shafts with flanged ends ("CVF" style). Should you prefer a driveshaft with open ends, a "CVO" style driveshaft is sold separately.

CVF drive shafts provide a smooth, low-friction transfer of power throughout a wide range of operating angles through which they were bent. Rubicon Express advises any Jeep being lifted over 3 inches should have these replacement drive shafts installed. Because the design is universal, Rubicon Express offers a large choice of CVF driveshaft lengths, and you'll need to know the size of the ones on your vehicle before ordering. Accurate measurements are obtained with the vehicle on the ground measuring center to center on the u-joint, making sure the slip stub is at the center of its travel.
