5150 AutoSport High Performance Main Bearing Set, BMW S38

5150 AutoSport's High-Performance Coated Main Bearing Set for BMW S38 engines is engineered for maximum durability and efficiency in high-performance builds. Coated by Calico, these bearings reduce friction, allowing the engine to generate more power while resisting wear from extreme stress and high RPMs.

The advanced thermal-resistant coating makes them ideal for forced induction and racing applications, providing reliable protection even during oil pressure loss, which is crucial for preventing catastrophic engine failure. Proven in both street and track conditions, these bearings consistently outperform OEM options, offering greater longevity and reliability.

Tech Notes: 

• As with all bearings, please check your tolerances and size before installation.
• Due to the specialized tools needed, professional install recommended.
• There are no returns available on any engine bearings.
