Lockright Locker Locking Differential Lunchbox

The POWERTRAX LOCK-RIGHT Locker is the original locking differential that could be easily installed in existing case assemblies without any special tools or setup equipment.

 The LOCK-RIGHT’s operation is fully automatic. Designed to send the engine power to the wheels with the most traction, the LOCK-RIGHT will help get you where you want to go. While traveling straight, the LOCK-RIGHT will lock the axles together similar to a spool. However, when the wheels need to differentiate in a turn, the LOCK-RIGHT will allow the outside wheel to rotate faster to complete the turn. The internal gears on the LOCK-RIGHT will overrun each other to allow this differentiation.


  • Fully automatic operation
  • 100% Locking
  • Easy installation
  • Budget friendly

The Powertrax Lock-Right Locker works well on the front axle of 4-wheel drive vehicles provided a couple of important guidelines are followed. The Lock-Right Locker should be used only on vehicles equipped with locking hubs on the front axle or with front axle disconnect. In addition, the vehicle must not be equipped with full time 4-wheel drive. Vehicles equipped with a Lock-Right Locker on the front axle should not be operated on the highway with the front hubs locked and 4-wheel drive engaged. Following these guidelines will ensure very acceptable on-road driveability while still providing maximum off-road traction.
