    Differentials

    Differentials aren't the most complicated items, but they are critical to the proper function and performance of your vehicle. If your WRX differential isn't strong enough to handle increased power, it could fail and leave you stranded. Properly applying torque to the ground in a high horsepower Subaru STI or WRX application requires upgraded limited slip differentials and high strength differential covers to keep it all in place. We even have the correct Subaru differential oils to make sure you complete the job right.
