Auburn Gear Limited Slip Differential

Auburn Gear Limited Slip Differentials

The Auburn Gear Limited Slip Differential employs an integral cone clutch side gear unit that creates friction with the carrier to drive both tires. The clutches will slip when one tire turns faster than the other. These are reasonably aggressive units that come in a High Performance and Pro version. The Pro version has more aggressive preload. Auburn also offers a D-Rex program to replace the unit should the clutches wear out.

Eaton Limited Slip Differential

Eaton Limited Slip Differentials

The Eaton Limited Slip Differential uses carbon disc clutch packs, preloaded by a central spring assembly behind each differential side gear. When torque input increases the clamping load on the clutch packs increases so that the chatter-free clutch packs grab and transfer power to both wheels. Muscle cars, hot rods and light duty off road vehicles should look to Eaton’s Limited Slip Differential for more rear end traction.

Eaton Detroit Truetrac

Eaton Truetrac

The Eaton Truetrac’s proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well. The unit performs like an open differential and uses friction between worm gears and the carrier to provide smooth power transfer to the tire with the most traction.

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.
