B38 High-Performance Rod Bearing & Rod Bolt Kit

The BMW B38 engine is known for reliability but also has a well-documented weakness: rod bearing wear and failure. Our 5150 AutoSport High-Performance Rod Bearing Kit is designed specifically for the B38, providing a complete solution to replace the factory connecting rod bearings and bolts with superior aftermarket components.

Kit Contents:

• Calico-Coated Rod Bearings reduce friction, resist spinning, and protect during cold starts
• ARP Connecting Rod Bolts 
• ARP Assembly Lubricant 
• Installation Sheet 

Unlike OEM bearings, our Calico-coated bearings deliver anti-friction and thermal-resistant protection, proven to withstand the demands of turbocharged, high-compression, and high-RPM B38 applications. Whether your B38 is powering a BMW i8, 118i, 218i, or MINI Cooper, this kit prevents common failures like spun rod bearings—a costly and all-too-familiar issue for B38 owners.

Key Benefits for BMW & Mini B38 Engines:

• Superior protection against oil starvation and cold-start wear
• Thermal-resistant coating for forced induction and tuned applications
• Reduces risk of engine failure and downtime
• Trusted by high-performance builders and daily drivers alike

For anyone rebuilding or maintaining a B38 engine, this kit provides confidence, durability, and performance far beyond factory parts.

Tech Notes:

• Always verify tolerances and dimensions before installation.
• Professional installation is strongly recommended.
• Engine bearings are non-returnable.
