Engine Main & Rod Bearing Set +0.50mm Audi A6 A7 A8 Q7 Q8 S4 S5 SQ5 3.0L EA839

This comprehensive bearing set provides a complete solution for high-performance Audi 3.0T EA839 engines requiring a major bottom-end restoration. When a crankshaft experiences severe wear or damage to both the main and rod journals, professional machining to a second undersize is often the only way to save the core. This +0.50mm (+0.020in) oversized set includes both crankshaft main bearings and connecting rod bearings, precision-engineered to compensate for the reduction in journal diameter. Built with high-strength, multi-layer materials, these bearings restore critical oil clearances and ensure stable oil pressure across the entire rotating assembly. Replacing both sets simultaneously ensures uniform clearances and long-term durability for heavily machined crankshafts in turbocharged V6 applications.
