ARP 207-2501 Harmonic Balancer Bolt Kit with 12-Point Head

ARP's high-performance harmonic balancer bolt kit is engineered to withstand the extreme forces generated as the crankshaft flexes and twists during operation. These ultra-strong bolts are rated at 200,000 psi tensile strength, allowing you to apply maximum clamping force to ensure the harmonic balancer remains securely locked in position.

Key Features:

• 200,000 psi rated chrome moly steel construction for superior strength and durability
• Extra tall 12-point head design accepts deep sockets and prevents head stripping
• 1/4-inch thick wide area washer distributes clamping load evenly
• Integrated 1/2-inch square drive forged into bolt head enables engine rotation with standard ratchet or breaker bar
• Manufactured from heat-treated 8740 chrome moly steel
• Heavy-duty black oxide finish for corrosion resistance

The square drive feature built into the bolt head allows technicians to easily rotate the crankshaft assembly using any standard 1/2-inch drive tool, eliminating the need for additional rotating tools during engine assembly or service. This precision-engineered fastener solution provides the reliability and peace of mind demanded by professional engine builders and performance enthusiasts.
