The Ford 8.8” rear end is known for being extremely robust, so we decided to make a conversion kit to convert your 08-21 STI or 08-14 WRX to this stronger rear end. This is ideal for high horsepower Subarus that need to put the power down without breaking parts. It includes custom pro level axles rated to 1000 HP, an aluminum driveshaft, diff bushings, brackets, and either a LSD or spool rear end.
