GM LS 12pt Main Stud Kit Gen-3/LSX

The GM LS 12pt Main Stud Kit Gen-3/LSX is designed for serious LS engine builders and high-performance mechanics who require reliable fastening solutions for factory or modified block architectures. This kit is particularly beneficial for those pushing higher boost levels or running aggressive cam profiles, as it replaces the factory main bolts that are not suited for extreme power applications.

The 12-point main stud design enhances grip geometry, allowing for more precise torque application and reducing the risk of fastener slip during critical clamping sequences. Manufactured from premium alloy steel, these studs are engineered to maintain consistent preload under thermal cycling and detonation events, ensuring that main caps are securely seated without overstressing the block or studs.

This kit is compatible with LS1, LS2, LS3, and LSX Gen-3 engine platforms, making it an excellent choice for street, forced induction, and racing applications. By upgrading to this main stud kit, builders can enhance the reliability and performance of their engine builds, safeguarding their long-block investment.
