OX Lockers are selectable differential lockers that feature a unique cable shifting mechanism for durable, reliable, safe, and easy locker engagement and disengagement. Each unit comes with a proprietary heavy duty differential cover that not only protects your differential, but also holds the shift cable (or air solenoid) and the OX locker's shift fork. With many different lengths of cable available and three different shifter options OEM and custom installations are made easy. Each locker is manufactured in the USA from forged 8620 heat treated steel (the same material used to make ring and pinion gears) and encases 4 spider gears for maximum strength and durability. The locking ring and locking gear used in the OX Locker feature back-cut teeth for superior locking force and accidental locker disengagement prevention. If you're looking for a heavy duty, long lasting, selectable locker that is easy to install, then the OX Locker is the right choice for you.

Choose the Right Cable Length
To select the proper OX shifter cable length measure the path of the cable to the shifter or actuator mounting location while making sure to avoid sharp edges and high heat areas and maintaining large radius turns to ensure smooth shifting. When in doubt, go one cable size longer. The table below also provides common cable lengths for vehicles.

Heavy Duty Differential Cover Included
While many electric and air operated lockers require a hole to be drilled through the axle housing for running a wire or air line, the OX Locker comes with a heavy duty differential cover that houses the locking mechanism and comes pre-drilled and threaded for the shifting cable. Not only does this make the locker easier to install, it means that you get a free diff cover upgrade with every purchase.

Mechanical, Air, or Electric Shifting
Unlike any other selectable locker on the market today, the OX locker allows you to engage or disengage your locker manually or by the flip of a switch. Standard equipment for the OX Locker is a manual shifter that allows for easy installation and simple, fool-proof operation. An electric conversion kit is available to replace the manual shifter with an electric actuator for shifting via a dash mounted switch while the air shifter does away with the shift cable altogether and uses and auxiliary air supply to do the shifting for the ultimate low profile installation.

Emergency Drive-Away Lock
Another unique feature of the OX Locker is the ability to mechanically engage the locker by installing an OX Drive-Away Lock (sold separately and highly recommended by Filthy Motorsports) that replaces the shifting cable and permanently engages the locking mechanism. The lock is easy to install and is perfect for trail repairs in the event that the shifting cable breaks or for situations where a locked differential is needed for extended periods of time.

3 of 5 Buyer Beware January 17, 2018
Reviewer: Andrew from IL United States  
Cons: This locker did not fit into my Chrysler 8.25 differential housing. Before I could adjust the backlash to be within spec the small cap of the locker was contacting the housing. This is with a 41 tooth (4.10) ring gear which is exactly the same with as stock. I ground the housing down to accommodate the carrier with backlash at .007, but when test fitting the shift fork it to required grinding to fit into the housing. All around poor fitment by design for this application. I did cross reference all the individual P/N of the locker to what is called out on the OX USA website and they all matched up.

The diff cover has the bolts recessed and no accommodation was made for the parking cable bracket which attaches to the top center bolt of the diff cover. This bracket also had to be modified to fit in its proper place.

Pros: A lot of thought went into how to be able to remove the cross pin to allow installation of the c-clips once the ring gear had been attached to the carrier.
