VAC's High-Performance Coated Rod Bearing Sets for BMW B46 and B48 engines are engineered to handle the extreme demands of turbocharged street, track, and motorsport builds. Designed for BMW platforms including the F20 220i, F30/F31 320i/328i, F32/F33 428i, F36 428i Gran Coupe, F22 220i, and F45/F46 2-Series Active Tourer models, these bearings deliver proven bottom-end protection where it matters most.
Each bearing features a proprietary low-friction coating that reduces parasitic drag, helping your engine generate more power while increasing resistance to bearing "spin" under high load and high-RPM conditions common to modern turbocharged four-cylinder engines.
The advanced coating also provides enhanced thermal protection, making these bearings ideal for high-horsepower applications, forced induction builds, track use, and performance-oriented street engines. Tested and validated in both street and motorsport applications, VAC B46/B48 rod bearings consistently outperform conventional bearing options, offering extended service life, reliability, and confidence in every build.
