Locked And Loaded

AUSSIE-MADE AUTO DIFF LOCK TAMES THE TONNER.

- Mark Allen

THERE’S NO argument that lockers transform a 4x4’s capabilities, but the big argument is whether to put them in the front or rear diffs, or both. This depends greatly on the vehicle type and intended use, so there’s no correct answer.

The number one argument for not having a manually operated diff lock in the front of the Tonner – which sports a GQ Patrol chassis, suspension, and diffs – is the loss of steering the instant the locker is engaged. Given that, a manual locker is in the rear diff and an auto locker (a LOKKA from 4WD Systems) is in the front diff, and I should get more use and superior workings from this combination.

The auto locker in the front diff can be used all the time without sacrificing steering ability, and it helps the Tonner crawl through pretty much any obstacle. For extra assistance, I can flick the rear TJM Pro Locker into operation.
