Differentials play a very important role in all cars, they allow the car to corner and turn smoothly and
easily. As in any corner or arc of travel, the outside wheels must travel a greater distance than the inside
wheels. Under power, without rear differentials (solid axle) a car will tend to drive in a straight line and
cornering will be extremely difficult. Many racers use front spool or one way , this differs from the rear
as front wheels turn, the direction of force is applied in the direction the wheels are facing. Regardless,
many drivers are reverting back to using front differentials to improve front end performance. What
makes a good differential? It is based on precision meshing of bevel gears, perfect balancing, low
rotational mass and smooth operation. K Factory developed and produced differentials according to
The front differential cover is now light weight aluminum and hard coated to resist against oxidisation.
The covers are precision machined and lightened to reduce rotational mass, and this improves acceleration
and deceleration. The differential is also balanced, this in turn reduces vibration and helps improve traction.
