It's the Single Biggest Upgrade You Can Make To Your 4WD's Off-Road Capability - Without Spending Thousands!
Why an automatic LOKKA?
The LOKKA is always working. With a conventional locker, you have a go at a section of track, lift a wheel, get stuck, reverse back, engage your locker and then have another go. That doesn’t happen with the LOKKA.
With a LOKKA, it’s always engaged. You wont even know it’s done the work.
(and still automatically unlocks when you need to steer – see the video for how).

What’s The Difference?
Compare the simplicity, cost and operation of a LOKKA automatic diff lock with a manual lockers.| Feature | LOKKA | Manual Lockers |
|---|---|---|
| Compressor Required | No | Yes |
| Electrical Wiring | No | Yes |
| Driver-Operated Switches | No | Yes |
| Automatically Engages | Yes | No |
| Always Ready | Yes | Must be manually engaged |
| Installation | DIY friendly | Usually professional |
| Maintenance | Very low | More components to maintain |
| Purchase Cost | Lower | Higher |
More traction! Lower cost!

Before and After Fitting a LOKKA
Shauno from 4WD247 shows a solid before and after example of just how good the LOKKA is. Same vehicle, same section of track – before the LOKKA is fitted then after.
Thinking About Installing The Lokka Yourself?
Here’s a DIY video of a LOKKA going into the carrier on a GU Patrol. And a couple of little tricks you can use too.
How Does A LOKKA Work?
This video gives a pretty solid DIY explination of how a conventional diff works, and how the LOKKA works.
Here's the full length video Shaun did on the LOKKA.
A LOKKA is a fully automatic Differential Lock that does not require any manual operation. It relies on a simple mechanical design which makes use of two distinct sets of forces – the “ground driven” forces acting on a wheel when cornering (that force an outside wheel to turn faster) and the forces from the engine (power) turning the differential and axles.
The combination of these two sets of opposing forces and the LOKKA design allow the automatic engagement and disengagement of the driving gears when a vehicle turns or requires differential action.
Wheel slippage or a loss of traction can occur for many reasons off-road and include excess throttle, fast approach speeds, limitations in wheel travel (especially independent front suspension vehicles), weight transfer off drive wheels & slippery surfaces such as mud, sand, snow, shale, wet grass etc.
In many of these circumstances both the normal standard differential and LSD center will allow the wheels with the least resistance to spin. Thus the wheels with traction do not obtain any real drive and the vehicle will lose speed or stop. LSD centers might assist under these circumstances but only if they are in good condition and only if there is enough resistance on the spinning wheels to activate the clutch pack or gears to force drive to the wheels with traction. Even a new LSD will allow a lifted wheel to spin freely with no drive to the wheel with traction.
LOKKA overcomes the traction deficiency of the standard differential and LSD center to ensure that a 50:50 power split is achieved when driving, irrespective of ground (or air!) conditions, yet at the same time still allowing differential action when cornering on hard ground.
Whether fitted to front or rear or both differentials, Traction Performance is significantly improved in all situations.
LOKKA enjoys an excellent reputation for reliability throughout the world – sold in every continent, in all realms of 4×4 and 2×4 performance activity.
