What makes 12-point head bolts different from standard hex bolts?

12-point bolts have twelve points of contact for the socket, compared to six for standard hex bolts. This design often allows for better access in tight engine compartments and can distribute torque more evenly.

What material are these head bolts made from?

These head bolts are made from heat-treated 8740 chromoly steel. This is a strong and durable material commonly used in high-performance engine components.

Do these bolts come with any special installation instructions?

Always refer to the manufacturer's installation instructions for specific details regarding torque specifications and procedures. Proper installation is key to ensuring optimal performance and sealing.

Product Details

ARP is well-known for making strong fasteners, and this 12-point head bolt kit is a solid example of their work for Small Block Chevy GENIV LS9 6.2L engines. When you're rebuilding the top end of your engine, especially for a high-performance application like the LS9, using reliable head bolts is crucial for sealing the combustion chamber and keeping everything running smoothly.

This kit uses 12-point bolts, which can be easier to access in tight engine bays compared to traditional hex heads. They are made from heat-treated 8740 chromoly steel, a material known for its strength and durability, which is important for handling the pressures and temperatures inside an engine. ARP bolts are also centerless ground to ensure they are perfectly straight, which helps them seat properly and maintain consistent clamping force across the cylinder head. This attention to detail helps ensure a good seal and prevents leaks.

This kit is designed as a direct replacement for your stock head bolts, making installation straightforward. It's a well-built component that helps ensure the integrity of your engine's cylinder head sealing.
