Ferrari Electronically Controlled Differential Unit Kit

Maintaining the precise rear traction management your vehicle depends on requires components that meet the exact engineering standards Ferrari designed the system around. This Ferrari Electronically Controlled Differential Unit Kit is the factory solution for one of the most well documented failure modes found in early production models equipped with the electronic differential. When the small gear axles migrate out of position, they apply direct pressure to the differential locking clutch plates. This generates excess heat and wear that contaminates the gear oil and degrades the performance of the entire system.

This kit is sourced brand new directly from Ferrari and includes every component required to restore the electronic differential to factory specification. The kit contains brand new clutch plates, replacement gears, and a new housing. Ensuring that the repaired unit performs exactly as intended from the factory. Using the complete factory kit rather than individual aftermarket components guarantees correct fitment and eliminates the risk of introducing incompatible parts into a precision engineered system.

The failure this kit resolves is specific and well documented in the Ferrari owner community. In affected models, the axles for the small internal gears gradually back out of their seated position during normal operation. As they migrate, they contact and compress the differential locking plates. Creating friction and heat that would not otherwise be present. The resulting wear produces metal debris and black discoloration in the gear oil. These are reliable indicators that this failure is underway. A shutter or vibration felt through the rear of the car during low speed tight turns is another clear sign that the differential internals require attention.

This Ferrari Electronically Controlled Differential Unit Kit is designed for all Ferrari models that use the electronic differential system. It is particularly relevant for early 458 models, which are the most commonly affected by this specific failure. If your gear oil inspection reveals metal contamination or you are experiencing rear end shutter during parking maneuvers or tight cornering. This kit provides the complete factory repair in a single purchase.
