Abstract: A rotary force when applied to an axle causes the wheel (10) to turn but the vehicle itself reacts to this rotation with an equal and opposite force and rotates the vehicle in the opposite direction lifting the front of the vehicle when accelerating forward. A reactive arm (13) is fitted to the driving axle in a manner where it can use this reaction to the rotary force and redirect this force to a point on the chassis (18) where this force can be used to counteract the effects of this rotary force and of weight transfer caused by acceleration of the chassis.
