found this bit of info via google hope it helps.
Kindly find information about the release of our new Ironman Differential Locker.
The Ironman Diff Locker is manufactured in Australia in conjunction with Eaton Corporation and Harrop Engineering is a new age electro magnetic design which is maintenance free. covers the range of Toyota Landcruiser and Hilux-Fortuner and Nissan Patrols.
Ironman diff lockers are
• 4 pinion design
• Push button operation ( no air system or plumbing required )
• Maintenance free
• Driver controlled to provide full axle locking
• Assembly kit includes all wiring
• Fully Serviceable
The initial range of Ironman Diff Lockers covers the range of Toyota Landcruiser, Hilux and Nissan Patrol. It has been engineered to capture 100 per cent of available torque sending it equally to both ends of the axle.
When the Locker switch is activated, electric current is supplied to a powerful electromagnet. As the electromagnet is energized, a torque is created on a drag-plate that activates a ramping mechanism. The ramping mechanism, in turn, translates rotational force into the axial motion of a locking mechanism. The locking mechanism engages into slots or tabs on the differential side gear and locks the side gear rotation to the differential housing. The result is on-demand traction and a fully locked differential.
The Ironman Locker is built with precision gears that are designed to mesh perfectly providing strength and durability over a standard gear cut.
The Ironman 4x4 diff lockers are different to the ARB air lockers due to the following reasons;
1) No air lines required- this means no compressors needed, no air lines or damage to airlines, no chance of oil pumping up the air lines, no delay in engagement due to oil in air lines, no leaking diff seals due to pressurized diff, no solenoids, no air tank, no pressure switch, less power draw to engage the lockers.
2) Maintenance free- no servicing required, no seals to perish, no part to break down due to seals wearing metal parts, no double lip seals breaking down
3) Stronger diff casing than ARB - less run out when setting up the diff.
4) Less warranty issues.
5) The Ironman diff lock comes as a complete kit, diff centre and wiring loom, this is all required. With ARB you have to buy additional parts.
6) Ironman diff lockers are state of the art electro magnetic engagement. ARB’s air lockers require full time pressure.
7) The Ironman locker have very low power draw compared to the ARB air locker used with the compressor
8) The Ironman locker has less moving parts and therefore less prone to breakdown.
9) The Ironman lockers requires only 2 switches in the dash for engagement. The ARB locker requires 3.
10) The Ironman locker is much simpler to install than the ARB locker
