Billet Aluminum Rear Differential Mount Plate

This upgrade is particularly beneficial for high-horsepower vehicles where factory bushings can wear out quickly, leading to noticeable cracking and reduced performance. The kit includes ECS Tuning's Performance Polyurethane Differential Bushings, manufactured with a 95A Durometer Red Polyurethane and a Black Anodized 6061-T6 aluminum sleeve. These polyurethane bushings are more resistant to chemicals, ozone degradation, road salt, and general wear than factory rubber, offering a longer lifespan and a more direct connection between the differential and chassis. This translates to better power transfer, improved throttle control, and enhanced handling without the harshness associated with solid mounts. The plate itself is made from 6061-T6 billet aluminum with a Type II anodized finish for superior corrosion resistance and durability. The product comes with a Lifetime Replacement Program. This product fits the following BMW models: F80 M3 (S55 3.0L), F82 M4 (S55 3.0L), F83 M4 (S55 3.0L), F87 M2 (N55 3.0L), and F87 M2 Competition (S55 3.0L).
