Open DifferentialsAn open differential allows both tires to spin at different speeds. This is perfect on dry pavement when the vehicle corners and the axles turn at different speeds, but it doesn’t work very well when one or both tires lose traction. In this situation, the tire with no traction spins, and the tire with traction does nothing. Open differentials are available as complete units, or as separate cases and internals, from both OEM and aftermarket manufacturers. |

Limited Slip DifferentialsLimited Slip Differentials generate more traction than the open differential. Most Limited Slip Differentials, sometimes called posi’s or positraction differentials, use clutches to drive both tires, but allow the clutches to slip when the vehicle corners and the axles need to turn at different speeds. However, the Truetrac acts as an open differential but applies torque to drive the tire with the most traction. |

Locking DifferentialsLocking differentials use various means to lock both axles so that both turn all the time. Automatic locking differentials disengage when the vehicle decelerates for corners. Selectable lockers allow the driver to engage the locking differential with a button. A locker ensures that both tires turn in all driving conditions. Lockers are ideal for more extreme off road driving. Learn more about our Locking Differentials |

SpoolsSpools are a solid carrier that does not allow axle differentiation. Both axles turn all the time. However, spools can’t disengage like a locker, so the tires will chirp when the vehicle corners. Tire wear will increase. Spools are most often used in racing applications, and occasionally in off road applications.

Nissan Titan Locking Differentials
Two different types of locking differentials are available for the Nissan Titan Dana 44 Rear axle from West Coast Differentials. The Dana Spicer original factory electric locking differential is available for both 32 and 35 spline axles. Nissan dealers only sell the entire axle assembly (very expensive!). ARB makes a 32 spline Air Locker for the Nissan Titan. Both the factory electric locker and the ARB Air Locker are open differentials that can be locked by the flip of a switch. So both locking differentials offer the best of both worlds: smooth and easy operation on the street, and fully locked axles off road.
