DSS Direct Bolt-In 800HP Rear Axle - Subaru WRX STI (GDB)
Driveshaft Shop (DSS) builds axles for cars that see real power and real abuse, and this rear axle (SKU 510215, part number RA8528X4-V2) is rated to handle up to 800HP without the driveline becoming the weak link. It's a direct bolt-in unit, so there's no cutting, machining or adapting required to get it fitted to your Subaru WRX STI.
This listing covers the Subaru WRX STI (GDB), built for the 2004 to 2007 model years. It's designed as a straight swap for the factory rear axle, so your existing hardware and mounting points are retained.
Please note: This listing is for one axle only. A complete set requires two - please order a quantity of 2 if you are replacing both sides.
