ARP 150-2501 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 balancer as the crankshaft flexes and twists during operation. These ultra-strong bolts are rated at 200,000 psi tensile strength, allowing maximum clamping force to ensure the balancer remains locked in position under the most demanding conditions.

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
• Heavy-duty black oxide finish for corrosion resistance

Square Drive Capability:

This special version features a 1/2 inch square drive forged directly into the bolt head, enabling you to rotate the engine assembly using any standard 1/2 inch drive ratchet or breaker bar. This innovative design eliminates the need for separate tools when positioning the crankshaft during assembly or service procedures.

ARP balancer bolts are the professional's choice for high-performance and racing applications where reliability and strength are non-negotiable.
