The Trac Loc is a less aggressive, street-friendly clutch-type limited slip unit that is suitable for daily driven vehicles and mild off-road use. The clutches work to maintain synchronization between the tires, transferring more torque to the tire that has the best grip while reducing torque transfer to the tire that has less grip. Yukon offers replacement units and rebuild kits for select Trac Loc applications that re-claim the unit’s original performance.
