SBC Head Bolt Kit

The ARP SBC Head Bolt Kit (SKU: ARP134-3604) is a professional-grade fastening solution designed specifically for small-block Chevrolet cylinder head assembly. This kit is ideal for builders and enthusiasts who are constructing street engines, race applications, or performing complete engine rebuilds, addressing critical weak points in vintage and modified SBC architecture.

Manufactured from premium-grade alloy steel, these fasteners offer superior tensile strength and fatigue resistance compared to OEM hardware. The kit includes precisely engineered bolts with optimized thread geometry to ensure even clamping load distribution across the cylinder head deck surface. Additionally, ARP's proprietary shot-peening process enhances the strength of the bolt shank, reducing stress concentration at critical load points.

This SBC head bolt kit is suitable for a range of applications, including naturally aspirated, supercharged, turbocharged, and nitrous-assisted engines. Builders can expect reliable performance under high RPM loads and boost conditions, making it an essential component for both mild street builds and full competition engines. Installation requires standard hex-key tools and adherence to the precision torque sequence provided in the kit.
