ARP 234-2501 Harmonic Balancer Bolt Kit with 12-Point Head

The ARP 234-2501 harmonic balancer bolt kit is engineered to handle the extreme kinetic energy absorbed by the harmonic balancer as the crankshaft flexes and twists during operation. These ultra-strong bolts are manufactured from heat-treated 8740 chrome moly steel and rated at 200,000 psi tensile strength, allowing maximum clamping force to keep the balancer securely locked in position.

Key Features:

• 200,000 psi tensile strength for maximum clamping force
• 12-point head design accepts deep sockets and prevents head stripping
• 1/2 inch square drive forged into bolt head for engine rotation with standard ratchet or breaker bar
• Heat-treated 8740 chrome moly steel construction
• Heavy-duty black oxide finish for corrosion resistance
• 1/4 inch thick wide-area washer distributes clamping load
• Extra tall head provides improved socket engagement

This square drive balancer bolt eliminates the need for special tools when rotating the crankshaft assembly during service or installation. Any standard 1/2 inch drive tool can be used directly on the bolt head, making engine work more convenient while maintaining the exceptional strength and reliability ARP is known for.
