Harmonic Balancer Fastener Kits

A properly secured harmonic balancer is critical to engine stability and longevity—any slippage or fastener failure can cause timing issues and internal damage. This Mr. Gasket bolt is engineered with precision threads and cadmium plating to withstand...

The harmonic balancer is critical to engine stability—it absorbs vibrations from your crankshaft and protects your entire drivetrain from premature wear and failure. A factory or worn bolt can slip under load, compromising balancer alignment and risking...

The harmonic balancer is critical to engine stability and longevity—it absorbs crankshaft vibration that can lead to premature bearing wear and component failure. A quality fastener here isn't optional; it's essential for reliable power delivery and...

The harmonic balancer bolt is a critical fastener that directly affects crankshaft stability and engine longevity. A worn or substandard bolt can lead to balancer slippage, vibration, and potential catastrophic engine damage. This Moroso Grade 8 bolt...

The harmonic balancer bolt is a critical fastener that directly transfers engine power to your crankshaft—it must be engineered to withstand extreme rotational forces without failure. A substandard or worn crank bolt compromises engine reliability and...

OEM balancer bolts frequently fail under sustained high RPM and boost conditions, risking catastrophic crankshaft damage. ARP's chromoly construction and precise engineering eliminate stretch and creep, ensuring your harmonic balancer stays locked in...

The stock harmonic balancer bolt can fail under high RPM and forced induction loads, leading to catastrophic crankshaft damage. ARP's chromoly balancer bolt kit eliminates this weak point with OEM-grade fastening that handles sustained boost and extreme...

The harmonic balancer bolt is a critical fastener that endures extreme rotational forces and vibration in high-performance engines—factory hardware often falls short under sustained boost or aggressive rpm cycling. ARP's chromoly construction and precise...

A harmonic balancer bolt failure can mean catastrophic engine damage—and the stock fastener simply isn't engineered to handle high-RPM abuse or forced induction applications. ARP's chromoly square drive damper bolt delivers the clamping force and...

The harmonic balancer is one of the most critical fastening points on your engine—it handles extreme rotational forces that can shear inferior bolts under high RPM conditions. ARP's 134-2501 SBC Balancer Bolt Kit delivers the clamping force and material...
