Dana Press Release  /  March 18, 2019

Dana today announced the launch of its Spicer Trac-Lok limited-slip differential for Spicer S140 single drive axles, which will be available in June for medium-duty work truck applications.  The differential provides improved traction during unexpected wheel-slip events and utilizes a reliable five-pinion design to serve Class 6 applications.

The Spicer Trac-Lok provides improved traction capability without requiring switches, wires, sensors, air hoses or manual input from the driver.  During a slip event, it automatically sends approximately three times more torque to the high-traction wheel-end.  The Spicer Trac-Lok then returns to normal wheel-end differentiation as conditions change in order to deliver maximum vehicle handling.

"The Spicer Trac-Lok differential for Class 6 applications utilizes a proven design from Dana products in the Class 5 and light-vehicle markets.  Our team utilized an established Dana technology, making application-specific refinements and adaptations, to maximize benefits and increase productivity," said Mark Wallace, president of Dana Commercial Vehicle Driveline Technologies.  "We are pleased to now offer a Dana-developed commercial-vehicle version of the enhanced differential for medium-duty applications that improves vehicle performance and uptime."

In addition to providing automatic engagement and enhanced traction, the Trac-Lok device is lightweight and fully interchangeable with a Dana standard S140 axle differential.  Trac-Lok will be available on Spicer S140 single drive axle models with gross axle weight ratings from 17,000 pounds up to 21,000 pounds.  Simplifying installation and use, Trac-Lok does not require wiring, pneumatic connections, special lubricants, or additional friction modifiers.

The Trac-Lok limited-slip differential is supported by Dana Aftermarket, which will offer Spicer Trac-Lok differential retrofit packages for all S140 drive axle models currently in service.
