SBM Head Bolt Kit 6pt.

The SBM Head Bolt Kit 6pt from ARP is designed specifically for small-block engine builders and performance mechanics who require reliable fasteners capable of withstanding extreme combustion pressures and thermal cycling. This kit is essential for those rebuilding or modifying small-block engines, particularly in high-horsepower applications where factory hardware may fail.

Manufactured from premium alloy steel, these head bolts undergo a proprietary heat-treatment process that enhances their tensile strength compared to OEM fasteners. The 6-point socket head design ensures excellent engagement and minimizes the risk of rounding during installation, which is crucial when applying torque on tight engine blocks.

Ideal for small-block engine platforms, this kit is perfect for street performance, drag racing, and engine swap applications. Both professional mechanics and DIY enthusiasts trust ARP fasteners to provide the reliability needed during assembly, ensuring a secure fit that helps prevent gasket failure and cylinder head lift.
