Kenworth has added a new lightweight driveline option from Dana for its T680 and T880 truck models used in linehaul and regional-haul applications.

The OEM now offers the Dana SPL 250 Lite driveline, designed to be 25 pounds lighter than the SPL 250 XL driveline it replaces in the Kenworth lineup. The new SPL 250 Lite series is also designed to better support powertrain downspeeding, which requires numerically lower rear axle ratios that increase driveline torque values. The driveline can support 18,400 lbs.-ft. of driveline torque.

The Dana SPL Lite driveline uses common end yokes and universal joints with the rest of the SPL family to simplify the changeover to the driveline during service work. The Dana driveline is available with a choice of service-free or standard re-lube designs to accommodate fleet preference.

“Kenworth’s addition of the SPL 250 Lite driveline reduces weight and maintains durability, provides longer service intervals for powertrain components, and enhances comfort with a quiet and smooth ride that drivers will appreciate,” said Kurt Swihart, Kenworth marketing director.
