This is an optional Schumacher Pro Ball Differential. This differential is fully assembled and ready for installation.
A gear differential in the rear gives better drive out of a corner and more on power steering than a ball differential, but the ball differential is always easier to drive, and good in low traction conditions.
In the front a spool is the standard choice and the best option for most conditions. A gear differential will give more mid corner steering, but suffer on corner exit. Schumacher uses a gear differential on very tight twisty tracks.
