ARP 235-2501 Harmonic Balancer Bolt Kit with 12-Point Head

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

Key Features:

• 200,000 psi tensile strength for superior clamping force
• Extra tall 12-point head design accepts deep sockets and prevents stripping
• 1/4 inch thick wide-area washer distributes load evenly
• Manufactured from heat-treated 8740 chrome moly steel
• Durable black oxide finish for corrosion resistance

Square Drive Feature:

• Integrated 1/2 inch square drive forged into bolt head
• Enables engine rotation using any standard 1/2 inch drive ratchet or breaker bar
• Eliminates need for separate tools when manually rotating the crankshaft assembly

This professional-grade fastener solution ensures reliable harmonic balancer retention in high-performance and racing applications where engine振動 and stress levels exceed factory specifications.
