 +''DifferentialComponent'' is a type of ''PowertrainComponent'' that splits input torque between two or more outputs.\\ There can be multiple ''DifferentialComponents'' present on one vehicle and one differential can output to other differentials which is useful for 4WD setup with center differential.
 +
 +<wrap round important>Unused differentials should be removed. E.g. a front differential that none of the other powertrain components (transmission, other differentials, etc.) are outputting to should be removed, as only powertrain components that have a path to Engine are updated.</wrap>

 +===== Differential Types =====
 +
 +== Open ==
 +Torque in open differential is equally split between the left output and right output.
 +
 +== Locked ==
 +Locked differential keeps both outputs rotating at same angular velocity. 
 +
 +== Limited Slip ==
 +Replaces previous separate ViscousLSD and ClutchLSD options.
 +Torque will be sent to the slower spinning wheel, keeping the wheels locked, up to the slip torque value.
 +
 +== External ==
 +Can be used to assign an external differential delegate function.
 +
 +
 +===== Configurations: 4WD / 2WD / etc. =====
 +To achieve a specific drivetrain configuration, different differential layouts can be used. For example:
 +  * **RWD**: Set the Transmission output to a Differential whose outputs are rear wheels. 
 +  * **FWD**: Same as RWD, but with the Transmission outputting to a Differential whose outputs are front wheels. Remove any unused differentials.
 +  * **AWD/4WD**: Can be achieved through three differentials; front, rear and center. The center differential should output to front and rear differentials, which then output to front and rear wheels, respectively.
 +  * **Adjustable**: A configuration of differentials as in the AWD setup can be used, but with the center differential set to //Open// type. Adjusting the BiasAB slider on the center differential to 0 will make the car FWD and adjusting it to 1 will make it RWD, assuming the first output of the center differential is the front differential.
 +  * **8x8 and similar**: A trees of differentials can be built, which allows for setups such as 6x6, 8x8, etc. Example:
