Description

The Dana S111FTLR488CF is a Spicer Trac-Lok limited-slip differential carrier for S111 series medium-duty truck drive axle applications. It provides improved traction by limiting wheel-slip rather than fully locking, with automatic traction engagement to boost driver productivity and vehicle handling. It's designed for a longer lifespan with superior lifetime torque bias performance and no degradation. It's a seamless upgrade, retrofittable with existing S110, S111, S130, and S140 axles, requiring no wiring, pneumatic connections, special lubricants, or friction modifiers. It offers optimized handling with a torque bias of ~3:1 in a slip event and freely differentiates in normal operating mode.
