LOKKA Differential Products
LOKKA is a fully automatic Differential Lock that does not require manual operation. It doesn’t 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.
