For stock 2021 Rubicon, engage the rear lockers in 4H by pressing the Off Road button, holding the ESC (traction control) button for 5 seconds, and pressing the lock rear button. If you wire them for safety, place the spring on the piston and thread it into the swivel fitting on your shifter. Thread the swivel fitting until it touches the shift rod.

Aftermarket add-on lockers are increasingly popular, and Quadratec offers many options for every popular axle type. One of the most reliable long-term options is the ARB Air Locker, which relies on an on-board air supply set up in the form of a compressor or Power Tank CO2 system. These stout units work well in adverse conditions.

Do lockers engage automatically?

When a vehicle turns, the outside tire spins faster than the inside. An open differential lets axleshafts spin at different speeds, but always sends power to the tire with the least traction. If you lift a tire, that’s the side that spins. An automatic locker locks the axleshafts together when the vehicle is moving. The axleshafts can only spin independently when the vehicle is coasting. When turning under power, the inside tire will make a noise and the outside tire will slip. Also, an auto locker will engage or disengage when power is applied or removed, which can cause jerking, banging, and clanging. A manual locker lets you choose whether to lock or unlock the differential. This lets you drive smoothly on the road without losing performance off-road. The downside is that it costs a lot and sometimes it’s complicated to engage or disengage it, like with bulky cables or air lines. Here’s our take on the subject.

If you bust a shaft under power, you’ll probably damage an automatic locker. So, I’ll factor axle strength and tire size into the equation. I usually go for a Detroit Locker. They can increase the turning radius, but I can turn sharply by modulating the throttle during slow, slinky trail work. If I’m running a vehicle with unit bearings or no locking hubs, I’ll go for a selectable locker. I’ve never had a failure with a pneumatic locker, but I have had problems with seals, air lines, and other parts. It’s made me lean towards electric lockers. I like running wires through the diff better than routing a cable or plumbing an air system.
