Nissan Titan Locking Differentials

Posted by zenxeon on
West Coast Differentials has three different locking differentials available for the Nissan Titan Dana 44 Rear axle (M226-32 Spline). These options include the Dana Spicer original factory electric locking differential, Eaton’s Detroit Truetrac and the ARB Air Locker. Both the factory electric locker and the ARB Air Locker are open differentials that can be fully locked by the flip of a switch. The Detroit Truetrac is a smooth-operating limited slip. Axle modifications may be required to install a Truetrac in models equipped with the factory electric locker. These models have unequal axle lengths due to an offset cross-pin.
