BMW S65 High Performance Main Bearing Set

5150 High-Performance Main Bearings for BMW S65 V8 engines are engineered to meet the rigorous demands of high-horsepower builds.

These bearings feature Calico's advanced coating technology, which reduces friction, increases durability, and helps the engine generate more power by minimizing wear.

Unlike OEM bearings, 5150's bearings are designed to resist "spinning" under extreme stress, making them ideal for forced induction and racing applications.

The thermal resistance of these bearings ensures reliable performance under intense heat, safeguarding against sudden engine failure due to oil pressure loss.

With proven success on and off the track, 5150 bearings offer long-lasting, superior performance that outshines standard OEM options.

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.
