LOKKA Differential Locker

Lokka Differential Locker

LOKKA is an automatic differential locker that is invaluable for Off-Roading. Whether fitted to front, rear or both differentials, Traction Performance is significantly improved in all realms of 4x4 and 2x4 performance activity.

LOKKA Differential Products

LOKKA is a fully automatic Differential Lock that does not require manual operation. It doesnt have switches, external lines, electric or pneumatic controls of any sort. 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 4x4 and 2x4 performance activity.

Took the Prado to Saunders Gorge over the weekend for a little Lokka workout. Rutted and Rocky with some reasonable hill climbs. Lots of loose stuff and the rain had left some marks on the track as well. Lokka performed faultlessly, made the whole task of getting up some steep shaley inclines effortless. My mate Adrian came along as well with his 100 series Lokka's front and rear and he was really impressed as well. Much happier to ease up some of these rutted rocky slopes than use momentum to get through.

I have now done about 350,000kms of trouble free motoring on my Lokka diff in the rear of my Toyota Landcruiser. After breaking the spider gears for the second time in the diff, I decided on recommendation to fit a Lokka diff lock to my vehicle, and what a great decision that was.

That was the last time I removed the diff centre for repairs and is performing as good as the day it was fitted.

Not only has the Lokka 'bullet proofed' the diff, it has markedly improved the performance of the vehicle off road. I have found I don't need to engage 4WD as often as before fitting the Lokka and have managed to get out quite a few situations I wouldn't have if I didn't have the Lokka.

I would just like to reiterate, the Lokka has done 350,000km of sometimes quite hard driving and is still performing perfectly.

I have no hesitation in recommending the Lokka diff lock to anyone wanting to enhance the performance of their vehicle.

I just wanted to let you know how impressed I am with the new front LOKKA. I fitted it to my NJ Pajero approx. 3 mths ago & it has just blown me away with it's performance ever since. The main features & benefits for me are:

1. Improved Traction (especially when lifting a wheel)
2. Ease of installation
3. Automatic function - not having to reach for switches when in the thick of it
4. Cost Effectiveness
5. Combined with Free-Wheeling hubs, it has no impact on the blacktop

This has to be without a doubt the single best modification I've made to the Paj to enhance off road performance. I've actually reached the point where I forget it's there & end up taking my son & friend (also in Pajeros) places they aren't equipped to handle. Just an amazingly simple & effective piece of equipment. I would recommend the LOKKA to anyone looking for that extra off road ability.
