Installing SYE and CV Driveshaft on a Jeep Cherokee XJ

Once the SYE is installed, you need a matching CV driveshaft. Unlike the stock shaft, a CV (or double cardan) driveshaft has two u-joints working together at the transfer case end, allowing for much higher operating angles without binding. Brands like Adams Driveshaft and Ten Factory offer heavy-duty 1310 series CV shafts specifically for lifted XJs. Adams uses DOM tubing and either greaseable or solid non-greaseable Spicer u-joints, with extreme-duty versions rated for up to 38-inch tires. Ten Factory shafts are compatible with lifts up to 4 inches and come with a complete hardware set. Crucially, do not order a custom CV shaft until the SYE is physically installed on your vehicle—you will need to measure the exact running length between the transfer case yoke and the rear axle pinion to get the correct fit.
