No switch needed for Spicer limited-slip differentials
Dana’s Spicer Trac-Lok limited-slip differentials for medium-duty trucks promise to improve vehicle handling, traction, durability and performance.
Drivers don’t need to engage any switches, thanks to an automatic design, helping to address poor traction or instability during turns. It also places less stress on axle shafts, protecting components and limiting tire wear.
The Trac-Lok limits wheel slip rather than fully locking, and acts as an open differential. If a slip begins, the unit automatically sends triple the torque to the high-traction wheel end and then automatically returns to full differentiation when conditions change.
Design features include a five-pinion pair to support a variety of Class 6 and 7 applications. And Trac-Lok has no wiring or pneumatic connections. No special lubricants or friction modifiers are needed.
The unit can be retrofit with existing Spicer S110, S111, S130, and S140 medium-duty drive axles with no wiring, sensors, air hoses, or pneumatic connections.
