PERRIN knows it’s important to keep your rear end cool! So keep it cool with the PERRIN Performance Differential Cover. Made from high strength, heat-treated cast aluminum, our cover incorporates cooling fins to reduce oil temps, thus extending the life of your expensive differential. Additionally, the oil capacity is increased more than 30% over stock. All combined in a great looking design to positively accentuate your rear end!
Will fit the 2006-2009 Legacy GT Spec. B with some modification.
