Description

The Driveshaft Shop RA8528X4-V2 is a direct bolt-in rear axle upgrade for the 2004-2007 Subaru WRX STI. This axle is designed to withstand significant abuse and is rated for up to 800 horsepower, making it suitable for performance applications like drag racing, rally, and autocross. The product is described as a direct bolt-in installation. However, one source noted slight fitment issues. It is also explicitly stated that there is no fitment application data available for this product, and buyers are advised to verify fitment manually.
