Autonomous Delivery of Improved Traction Capability

PROBLEM
“Drivers are frustrated by frequent incidents of poor traction and a sense of instability during turns.”

SOLUTION
Spicer® Trac-Lok™ limited-slip differentials deliver improved vehicle handling by limiting wheel-slip rather than fully locking, and automatic traction engagement helps boost driver productivity.

Spicer Trac LokThe new Spicer® Trac-Lok™ limited-slip differential for S110, S111, S130 and S140 medium-duty truck drive axle applications provides improved traction, autonomously. This design innovation from Dana delivers improved productivity and vehicle handling within a lightweight, compact design.

For the most demanding applications, Dana also offers the option of a locking differential for Spicer S140 axles that delivers full-locking, maximum traction.

Limits wheel-slip for improved maneuverability
