Dana / Spicer SPL170X Journal and Bearing Kit – Heavy-Duty Driveshaft Repair Kit
The Dana Spicer SPL170X Journal and Bearing Kit (SPL170X-4X) is a premium heavy-duty driveshaft service component designed to restore the rotating connection between driveshaft yokes and the universal joint assembly on commercial trucks, vocational vehicles, and severe-duty applications. The journal and bearing kit replaces worn or damaged bearing cup and journal components inside a Spicer Life Series (SPL) 170X universal joint, helping eliminate driveline vibration, excessive play, clunking, and premature driveshaft wear.
Built for high-torque applications, the SPL170X series is engineered for fleets requiring durability, extended service intervals, and reliable power transfer through demanding operating environments including Class 6–8 trucks, construction equipment, refuse vehicles, buses, and vocational equipment. The SPL170 series is rated for approximately 17,000 Nm functional torque capacity, making it one of the most widely used heavy-duty Spicer driveshaft platforms.
