The Dana Spicer 73613X case assembly kit is a loaded Trac Lok differential carrier for the Dana 44, built for 3.73 and down gear ratios. Trac Lok is a limited-slip design, so when one wheel loses grip the carrier works to keep driving torque going to the wheel that still has traction.
It is supplied as a complete loaded unit rather than a bare case, with the internal parts already assembled in the carrier. Check your axle's ratio against the 3.73 and down range before ordering, and call us to confirm proper fit for your application. A genuine Dana Spicer part from Pro Gear and Transmission.
