Dana Incorporated (NYSE: DAN) 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. For more information, visit www.dana.com.
Dana will present a comprehensive lineup of Spicer Electrified™ systems, traditional driveline technologies, and other solutions for commercial vehicles in TMC booth 2801.
