BMW MINI B38 High-Performance Rod Bearing Set

The BMW B38 three-cylinder turbo engine is compact, efficient, and powerful — but like many modern BMW engines, it suffers from one notorious issue: rod bearing wear and failure. The 5150 AutoSport High-Performance Rod Bearing Set is engineered specifically for the B38 to solve this problem with durability and reliability that OEM bearings can’t match.

Each bearing is treated with a Calico anti-friction coating, reducing drag and protecting against the most common cause of B38 failure: spun rod bearings. This coating also provides exceptional thermal resistance, making these bearings ideal for everything from tuned daily drivers to track-prepped BMW i8s, 118i, 218i, and MINI Cooper B38 models.

Key Advantages Over OEM B38 Bearings:

• Friction-reducing Calico coating improves lubrication and wear resistance
• Thermal-resistant design protects under high boost, high-RPM, and racing use
• Safeguards against oil pressure loss and cold-start failures
• Proven performance and longevity in both street and motorsport applications

When it comes to reliability, the 5150 B38 rod bearings are a trusted upgrade for enthusiasts who demand more from their engines. Whether you’re preventing failures on a stock B38 or supporting a high-horsepower build, these bearings provide the insurance your engine deserves.

Tech Notes:

• Always check tolerances before installation.
• Professional installation is strongly recommended.
• No returns on engine bearings.
