About this part

Product Details

These main bearings are 0.05 undersize, meaning they are designed to be used when the crankshaft journals have been machined down by 0.05 inches to clean up wear or damage. King Engine Bearings uses a high-performance overlay that's applied over a steel backing for strength and durability. This overlay is designed to work well with various oil types and provides a solid foundation for your engine's rotating assembly.

When you're rebuilding an engine, especially one like the Hyundai G4HC or G 1.0/1.1L SOHC 12V, getting the bearing clearances just right is critical for oil pressure and longevity. These bearings are made to fit precisely, helping to ensure that your crankshaft spins smoothly within the engine block. They are a well-built option for anyone looking to restore their engine's bottom end.
