Construction & Design

The ARP Head Bolt Kit features a robust chromoly steel construction, known for its high tensile strength and resistance to stretching or fatigue. The black oxide finish not only enhances corrosion resistance but also provides a professional, finished look. The fasteners are precisely machined to ensure perfect thread engagement and consistent clamping force, which is vital for maintaining proper head gasket sealing and preventing head lift under high loads.

The design incorporates either a reduced wrenching hex head or a 12-point head, offering flexibility for installation and re-torqueing procedures. The washers included in the kit help distribute load evenly across the cylinder head surface, reducing the risk of damage and ensuring a secure fit. These features combine to deliver a reliable, high-performance fastening solution that meets or exceeds OEM specifications.
