Description
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 engine speeds. If you’re running a modified Ford engine, this is non-negotiable insurance.
