About this part

Product Details

This is a performance main bearing set from King Engine Bearings, sized at +.025 undersize. You get the main bearings needed to rebuild the bottom end of your Nissan VG30DE or VG30DETT engine. These bearings are built with a tri-metal copper-based material, which is a solid foundation for handling the stresses of performance applications. King has specialized in bearings since 1960, focusing on making them well-built and reliable.

The PMaxBlack overlay on these bearings offers improved load capacity, meaning they can handle more pressure without failing. They also feature Radialock, a design element that helps achieve optimal crush height during installation. Proper crush height is important for ensuring the bearings seat correctly and maintain oil pressure. This set is designed to fit a range of Nissan and Infiniti vehicles, including models like the 300ZX, J30, and Frontier.
