Construction & Design

The ARP Head Bolt Kit features a meticulously engineered design utilizing high-quality chromoly steel, known for its exceptional strength-to-weight ratio. The bolts are precision-machined with a controlled stretch design, which ensures consistent clamping force and reduces the risk of head gasket leaks. The black oxide finish not only enhances corrosion resistance but also provides a professional, finished look.

The reduced hex head design allows for easier access in tight engine bays and simplifies re-torque procedures, especially when valvetrain components are still installed. The 12-point head option offers additional engagement points for increased torque application and ease of installation in confined spaces. Each bolt is carefully tested for quality and durability, ensuring long-lasting performance under demanding conditions.

Installation & Fitment

The ARP Head Bolt Kit is a bolt-on solution that requires no special modifications. Installation involves removing the cylinder head, cleaning the threads, and torquing the bolts to the manufacturer’s specifications using a calibrated torque wrench. The reduced hex head design allows for easier access in tight engine compartments, and the included washers ensure proper load distribution. No valvetrain removal is necessary when re-torqueing, streamlining the process during rebuilds or head swaps.

Always follow the recommended torque sequence and specifications provided by ARP or your engine manufacturer to ensure proper installation and optimal performance. Proper tightening and re-torque procedures are essential for achieving the full benefits of these high-performance fasteners.
