The stock RX8 differential case is a known weak point, prone to flexing and even breaking under hard use. This high-rigidity cover from Revolution is a comprehensive solution, with an average thickness of 5–10mm (compared to 3mm OEM) and upgraded bolts that act as knock pins. It ensures your side bearing preload and gear contact remain stable, extending the life of your differential.
- Increases differential oil capacity by 750cc for improved cooling.
- Features large cooling fins to further stabilise oil temperatures.
- Significantly increases the rigidity of the differential housing to prevent flex and failure.
- Upgraded bolt system acts as dowels to securely locate the cover and add strength.
- Includes a service hole to allow for the installation of an external oil cooler.
This is the ultimate upgrade for drivetrain reliability. It gives you the confidence to launch the car and use it aggressively, knowing that the differential is properly supported and lubricated to handle the stress.
