B48 Main Bearing Set, High-Performance

Built specifically for the BMW, Mini Cooper, and Toyota B48 engine platform, 5150 AutoSport Calico Coated Main Bearings are engineered for demanding performance builds where reliability and strength are non-negotiable. These bearings are coated by Calico with a proven dry-film lubricant that reduces friction, enhances wear resistance, and offers superior performance under high stress. Whether you're running a high-boost turbo setup, pushing the limits on track, or building a street car with big power goals, these main bearings are made to handle it. The thermal-resistant coating helps safeguard the engine during low oil pressure events—minimizing the risk of bearing failure common in stock components under extreme conditions. Tested in competitive and high-horsepower B48 builds, 5150 main bearings deliver consistent performance, long-term durability, and added peace of mind where it matters most. Tech Notes: Always confirm bearing size and clearances before installation. Professional installation is strongly recommended due to the precision tools required. No returns accepted on engine bearings.
