SPL® 350 U-Joint Puts the Life into Downspeeding Applications

The right driveshaft and inter-axle shafts with robust and durable components can handle the added input torque with even greater reliability. That's why Dana engineered the Spicer Life® Series with an exclusive design that accommodates faster axle ratios without sacrificing life.

Engineering Driveshafts for Lower RPMs

Spicer Life® Series u-joints are engineered, tested and proven to meet the torque demands being placed on drivetrains. While engine downspeeding offers increased fuel economy and decreased emissions, the faster axle ratios needed to accommodate the lower RPMs result in additional torque in the drivetrain, placing much higher stresses on the main driveshaft, axles, and inter-axle shaft.

SPL® 170 and SPL 250 universal joints are also available in service-free* options, which are lubricated for the life of the part. Permanently lubricated u-joints help keep your overall operation costs low while still offering the durability and dependability you expect from Spicer. Service-free* options are ideal for heavy-haul applications and are capable of meeting the requirements of future fast axle ratios.

    * Inspections must be performed at each interval to check for wear, damage or looseness that could affect lubricant life and lead to driveline failure.
