Ashcroft LT230 AATB Diff
We are very pleased to offer an Ashcroft Automatic Torque Biasing centre differential for the LT230T. A little background on the LT230 centre diff. The centre diff is there to allow the props to turn at different speeds when cornering to stop drivetrain wind up. The speed difference is quite small and the centre diff gears are only designed to cope with these low speeds. If you are Off Road on snow or ice and you get wheelspin from one front wheel, what will happen is the rear prop will not be moving, the front will thus be going double speed, this means the small centre diff gears will be spinning like fury and after a matter of only a few seconds the planet gears will friction weld to the cross pins and the gears will fail etc. Of course in this situation the centre diff should be locked to avoid failure. There are instances when it's not convenient to keep the diff locked or to constantly lock and unlock the diff as the available traction dictates, i.e, when racing fast on a low traction surface, the vehicle will not handle well when locked but is likely to wheel spin when unlocked. Another example of where the AATB would help would be when rapidly changing from high to low traction surfaces, i.e. when driving on snow or ice, In both of these examples the AATB will limit the amount the difference in propshaft speed and transfer torque to the axle with traction. The two big advantages are increased traction when unlocked and eliminating the weakness of the stock unlocked centre diff. Note the AATB centre can still be locked like the stock unit when required, locking the diff is still advised when prolonged wheel spin is anticipated. When an AATB is ordered to be built within a rebuilt LT230 the price will be reduced to £ 300. We make 2 different types of these as there are 2 different diameters of spline used for the high/low selector hub, the one you need can be identified by either the serial number or vehicle type, Type A is 54mm dia, Type B is 58mm dia Type A - RRC, Disco 1, all Defender pre TD5, Serial numbers starting 20D, 22D, 25D, 26D, 28D, 29D, 36D, 37D Type B - Disco 2, TD5 and TDCi Defenders, Serial numbers starting 41D, 42D, 43D, 57D, 60D, 61D, 62D, 68D, 69D, 70D, 80D, 81D We recommend using EP80/90 oil. Note : Due to the nature of the AATB diff we do not recommend the vehicle is brake tested on rollers, ask for a decelerometer to be used instead. | Select options | |

HD Cross Pin
Heavy Duty LT 230 Cross Pin The standard LT230's have a two piece cross pin in the centre diff, this is two shafts with a cut out in the centre so they can overlap. We make this one piece cross pin which is much stronger. These can be specified when ordering a LT230 or sold separately. | Add to cart £50.00 | |
