Cusco Subaru STi / WRX / FXT Rear Differential Carrier - 6A1 489 A

Cusco 6a1489a Subaru STi / WRX reinforced rear differential carrier with HD bushings. The Cusco reinforced rear diff carrier is a direct replacement for your OEM. It will tighten up your drive-train slop and make a very noticeable difference compared to OEM. This can be used on street or track Subaru's and will help improve traction and stiffen the rear of the car. This will not add noticeable NVH so street cars will still be enjoyable but better planted.
