Electric Diff Lockers OVERVIEW

The Electric Diff Locker is a ‘tuff as nails’ selectable diff lock for applications where 100% reliable off-road traction is required. Traction on demand! Incredible 6 Year Warranty.

Search Lockers By Vehicle

The revolutionary electromagnetic engagement mechanism will lock the front and/or rear differentials at the flick of a switch. 100% standard open to 100% locked in an instant.

The Electric Locker uses an electromagnetic locking centre to lock one of the 4320 chrome alloy side gears to the 8260 steel carrier. The locking mechanism is tested to 17,000nm of torque, without failure.

Tuff as nails!

Once one side gear is locked, the other planetary gears cannot rotate, effectively locking the two axle shafts together. Air Locker works on the same principle but uses air pressure from an on-board compressor instead of an electromagnetic force.

Electric Lockers perform as an open differential when not locked, meaning it has no effect on driveability and the vehicle drives like normal. With the push of a button there is virtually instant locking, and the precision-forged gears lock to provide a 50-50 power split to each wheel.

Suitable for Front and/or Rear application.

The Electric Locker centre replaces the existing carrier, no matter if it is an OEM LSD or a standard open carrier. It even replaces some OEM Lockers. In effect, the existing ring gear or crown wheel is swapped to the new Electric Locker carrier.

Many applications have new carrier bearings included in the kit. The crown & pinion gear relationship does change and the lash needs to be adjusted to finalise the installation. Comprehensive DIY Instructions are included, but seek professional assistance if you are not sufficiently experienced.

All OE recommended oils for the differential are compatible with Electric Locker, as are any additives like Teflon, Nulon, STP etc.

Electric Diff Locker Switchable Traction:

  • Positive electromagnetic locking
  • Precision-forged gears
  • 4 Pinion design
  • Many kits supplied with Carrier bearing
  • Drop-in installation
  • Superior re-buildable design
  • Requires no external module, compressor or hoses
  • Push button traction

Electric Diff Locker Frequently Asked Questions

Electric Lockers have a sliding locking ring which locks one side gear to the carrier. The axles fit into the side gears. Once one side gear is fixed, the other planetary gears cannot move, so the axle shafts are effectively locked together. The Electric Locker is normally unlocked, so the vehicle drives like normal.

Yes. Electric Lockers are 100% positive locking, there is no slippage when locked – there is a mechanically solid engagement of one side gear to the carrier via the locking ring. This means that you get 100% of drive and traction to both wheels.

That depends on your ability.

The hemisphere replaces the factory Open, LSD or OE Locker and the ring gear lash does have to be adjusted, so if you are not technically able, a regular workshop, 4×4 workshop or differential specialist is required. Very Detailed Instructions are supplied.

Expect from 5 to 7 hours for most fittings.

No. Use the recommended oil for the differential. Differential additives can be used.

No. The ring gear is not changed, but it represents a good opportunity to rebuild the differential or change the ratio to adjust for over size tyres.

Our Electric Locker is manufactured from high quality components, including 4320 chrome alloy locking ring, side gears and 8260 steel carrier. The locking mechanism is tested to 17,000nm of torque, without failure. This means the Electric Locker can easily withstand the forces generated from modified engines and over-sized tires, often found in off-road vehicles.

Our Electric Diff Locker has a 6 Year Warranty.

Length of life will depend on many factors, particularly its service regime, but due to its design and high quality componentry, it will last longer than the original differential.

Our Electric Locker can be fitted to Full Time 4WD vehicles, for On-Road use, Front or Rear, without conversion to Part Time 4WD.

Why fit to the front?

  1. Off-roading is all about Traction. Traction loss most commonly occurs when hill climbing, not hill descending. The steeper the slope the greater the weight transfer from the front to the rear wheels. With more weight pushing the rear wheels into the terrain, providing greater natural traction, the less likely they will break traction first. With less weight, the front wheels break traction first.
  2. Most modern 4×4’s have Independent Front Suspension. IFS vehicles have limited wheel travel so they tend to lift a wheel into the air – results in no engine power to the wheel in the ground – unless it has a locker fitted. Once one front wheel is spinning, all the driving load is transferred onto the rear wheels, and this sudden transfer of load encourages the rear wheels to break traction. Remember, the aim of off-roading is NOT to break traction.
  3. Track surface deterioration – the tree root step-up, the muddy/sandy/shalely section of the track, is encountered by the front wheels first. (assuming you’re going forwards!). So one of the front wheels will lose traction first as they hit this section. If one front wheel spins, the other stops being driven, the load is rapidly transferred to the rear wheels, again, encouraging them to break traction. Share the load across both front wheels with 100% locked, 50/50 split drive with E-Locker engaged.
  4. There is no change to on-road behavior.
  5. On really slippery surfaces, like snow and mud, the front fitted E-Locker will provide positive directional steering, giving control back to the driver, rather than drive coming from the rear trying to spear the vehicle in the straight ahead.
  6. Two E-Locker is better than one!
    Putting any locker into the rear does nothing to stop the front losing traction, it just makes the vehicle a lot better 2×4, better at pushing from the rear. Even if you can only keep one wheel driving at the front, you will probably have three wheels working and spreading the driving load over the greater surface area of all three tires.

Yes. Electric Lockers operate in forward & reverse, up & down hill.

Yes, it will effect your steering, to a varying amount depending on the obstacle or surface. There are situations where steering and handling will change including some understeer and stronger self-centering of the steering. Electric Lockers fitted to front and rear can cause inter-axle windup and this can affect steering to a greater extent – stronger self-centering, greater understeer and larger turning circles.

There is a very slight ‘click’ on engagement and dis-engagement, otherwise there are no noises.
