ARP 208-2501 Harmonic Balancer Bolt Kit with 12-Point Head

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

Key Features:

• 200,000 psi tensile strength for exceptional holding power
• 12-point head design accepts deep sockets and prevents stripping
• 1/4 inch thick wide-area washer distributes clamping load evenly
• Extra tall head provides secure tool engagement
• 1/2 inch square drive forged into bolt head enables engine rotation with any 1/2 inch drive ratchet or breaker bar
• Constructed from heat-treated 8740 chrome moly steel
• Heavy-duty black oxide finish for corrosion resistance

The integrated square drive feature makes this balancer bolt especially useful for rotating the engine assembly during service procedures, eliminating the need for separate turning tools. ARP's precision manufacturing ensures proper thread engagement and reliable performance in high-stress applications.
