1806BILLET ASHCROFT ATB CENTRE DIFF

BILLET ASHCROFT LSD CENTRE DIFF, SUIT ALL LAND ROVERS WITH THE LT230 TRANSFER CASE (DISCO 1 & 2, RR CLASSIC, DEFENDER TD5 AND PUMA.
HUGE REDUCTION IN DRIVE LINE BACK LASH, MORE STABILITY AND LESS WEAR IN THE TRANSFER CASE, THE ULTIMATE UPGRADE FOR THE LT230 CASE

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 Ashcroft Torque Biasing Centre 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 Ashcroft Torque Biasing 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 Ashcroft Torque Biasing centre can still be locked like the stock unit when required, locking the diff is still advised when prolonged wheel spin is anticipated.
