The Cusco Reinforced Differential Carrier is perfect for those of you who enjoy spirited driving, or the occasional weekend track day. This component has been designed to improve traction and reinforce the multi-link points which strengthens the integrity of the rear end and stabilizes the rear end under heavy cornering. This results in better driveline response without the loss of torque.

This component has been fabricated using high-grade metals and box type construction that is hand welded before getting powder-coated in Cusco's flagship blue color. Additionally, this differential carrier will come with Cusco's premium rubber bushings that are pre-installed and will be ready for installation.

Support your rearend!

This was a fast job with minimal tools. The instructions were in Japanese but all you need to know is the logo goes to the front and if you need to use the spacers they go on top. Installed on a 2019 Crosstrek and it even works with the Primitive diff skid plate!
