| The Adjustable Differential |
| As stated on the main section page, the term adjustable differential is somewhat of a misnomer as the majority of differentials have some degree of adjustability. |
| The adjustable differential we refer to in this article is a relatively simple derivative of the open differential. Although there are different designs and implementations they work by the same principle as the example used here. |
| Please note that this is not a real differential - the image serves to demonstrate a principle. |
| The image on the right shows a cross-sectional view of an adjustable differential that uses Belleville Washers to apply pressure to the sun gears. |
| This increases the resistance between the gears and stiffens the action of the differential. |
| As it is adjustable, the 'diffing out' associated with the open differential can be reduced or completely eradicated. |
| The adjustment is provided by a modified grub screw which allows quick and easy access for track side adjustments. |
| As far as the internal parts are concerned, they are the same ones that are fitted inside a normal open differential. |

|
| If not present on the non-adjustable type, steel thrust washers are fitted behind the the sun gears to stop the forces generated by the belleville washers wearing the casings. |
