ARP 120-3601 Buick 350 Hex Head Bolt Kit

The ARP 120-3601 head bolt kit is specifically engineered for Buick 350 cubic inch V8 engines, providing superior clamping force and reliability compared to stock fasteners. This complete kit includes all the head bolts needed for a proper cylinder head installation.

Key Features:

• Black oxide finish for corrosion resistance and professional appearance
• Hex head design for easy installation with standard tools
• Manufactured from premium 8740 chromoly steel for exceptional strength
• Heat-treated to 200,000 PSI tensile strength rating
• Precision CNC-machined threads for accurate torque readings
• Includes premium-quality ARP thread lubricant for proper installation

ARP fasteners are roll-threaded after heat treatment, which creates a smooth radius at the root of each thread. This manufacturing process significantly increases fatigue strength and ensures consistent, reliable performance in demanding applications. Each bolt is individually inspected to meet ARP's strict quality standards, making this kit ideal for both stock rebuilds and high-performance engine builds.
