Dana Spicer SPL100X Spicer Life Series Universal Joint
The Dana Spicer SPL100X Universal Joint is a heavy-duty, non-greaseable driveshaft U-joint designed for Dana Spicer SPL90 and SPL100 Series driveline applications. Part of the Spicer Life Series, the SPL100X uses a sealed, lube-for-life design that eliminates routine lubrication requirements while helping provide long service life, increased bearing capacity and reduced maintenance.
The joint features a precision-manufactured steel cross, four round bearing cups and external snap-ring retention. Its 1.625-inch bearing-cap diameter and 4.957-inch outside span must be matched to the existing driveshaft yokes before installation. Dana identifies SPL100X as the engineering part number for its non-greaseable SPL100 driveshaft U-joint kit.
