Mechanical Limited Slip Rear Differential for Alfa Romeo Giulia Quadrifoglio

World Exclusive!

Take your Alfa Romeo Giulia Quadrifoglio to the next level with the new Mechanical Limited Slip Rear Differential, a unique kit worldwide that allows the complete transformation from the electronic system to the traditional mechanical system.
An absolute exclusive, designed for true driving enthusiasts who want to rediscover the pure and direct feeling of mechanical traction, without electronic filters, without compromises.

Unique in the world: the complete transformation

This complete axle shaft kit allows full conversion to the mechanical limited slip differential, offering a more authentic, precise, and engaging driving experience. It is the only system available on the market that enables this modification on the Giulia Quadrifoglio, making it a worldwide exclusive product.


Track Performance and Sensations

The mechanical differential guarantees optimal traction and immediate torque distribution between the rear wheels, improving cornering stability, entry precision, and throttle control.
Compared to the electronic system, it offers a more direct and progressive response, giving the driver a raw and genuine feeling, ideal for those who see driving as an art.

On the 2023 Giulia Quadrifoglio debuts a multi-plate mechanical limited slip differential, designed to optimize traction and dynamic response.
The system features a locking calibration of 35% under acceleration and 50% on deceleration, values that determine how much the differential limits the speed difference between the two rear wheels.
The internal structure uses dedicated clutch packs and ramp angles, which modulate locking based on driving torque and deceleration.
The result is a more direct and predictable traction management: the rear end follows the front end's inputs more promptly and, on corner exit, the thrust is cleaner, continuous, and fully mechanical, without electronic interventions correcting the dynamics.

Tested on track with excellent results, where the electronic differential heats up and starts to lose efficiency, the mechanical remains unchanged throughout the session.


Main Product Features:


Driving Experience for Purists

The new mechanical differential allows you to actively manage traction through the accelerator pedal, making every corner an exercise in precision and control.
