Diff Lock

You can't turn those front wheels while your lockers are engaged ......

Of course you know that ..

Those air lockers (and the air lines) are pretty sturdy if you ask me. The ARB compressor can also act as your inboard tyre inflator, should you need to lower tyre pressures.

Cost is another thing though ...

The beauty of this type of locker is that, unlike the selectable one, you CAN turn the wheels anytime you want. I've recently tested the thing in cavinti and it works as expected. So far, the only drawback is that now there is a noticeable vibration from under my feet approaching 100kph. But who would drive a lifted truck that fast?

Yep, the ARB lockers are sturdy indeed. But the install, says the shop owner, can easily be messed up with and that is where the real problem is. As simple as the 'improper' cutting of the air lines can cause a leak.
