ARB Air Lockers
The ARB Air Locker is a selectable locking differential that is pneumatically engaged by a driver controlled switch. They provide the best of both worlds: open differential action on the street for smooth driving and fully locked traction when needed. The durable ARB Air Locker is the unit of choice for many rock crawlers. They are available for over 100 differential applications. Read more about ARB Air Lockers.

Detroit Locker
The Detroit Locker is an automatic locking differential that maximizes traction by delivering 100% of the torque to both drive wheels. It is engineered to keep both wheels turning while in drive mode, but unlocks under deceleration to allow axle differentiation. These units are very durable and are available for most applications. The Detroit Locker is a proven choice for more extreme off road driving. Read more about Detroit Locker

Eaton E-Locker
The Eaton E-Locker performs as an open differential until you need more traction. The push of a button solves almost any traction problem. Designed expressly for 4-wheel drive systems to give you the ability to lock or unlock the differentials when necessary. When locked the Eaton E-Locker performs as a full locker, capturing 100% of available torque and sending it equally to both ends of the axle. Learn more about the ELocker from Eaton

Lock Right
The Powertrax Lock Right replaces the spider gears in an open differential carrier, making the unit an automatic locking differential. These light duty units are less expensive and easier to install than other locking differentials. Read more about the Powertrax Lock-Right

Auburn Ected
The ECTED Max is a selectable traction device with an on/off switch mounted near the driver. When in the off mode, the unit operates in limited slip mode. When switched on current is sent to an electromagnetic coil that ramps up ball bearings, locking the clutch packs, and providing a solid axle assembly. These units are great off road or on the strip.
