Reliable Crank Pulley Security for Honda B-Series

The harmonic balancer is a critical component of your Honda B-Series engine, and keeping it securely fastened is non-negotiable. The Auto Racing Products (ARP) 208-2501 Harmonic Balancer Bolt is designed to provide superior holding power compared to the factory bolt, ensuring your crank pulley stays exactly where it needs to be, even under high-RPM racing conditions.

Technical Specifications

  • Thread Size: 14mm x 1.25
  • Length: 1.350 inches
  • Head Type: 19mm 12-point head for easy installation
  • Material: 8740 Chromoly steel
  • Finish: Black oxide coating
  • Compatibility: Honda B16 and B18 engines

This bolt is manufactured with a wide-area flange to distribute the load evenly, preventing the pulley from wobbling or loosening. The high-strength chromoly construction ensures that the bolt can withstand the vibration and torque loads inherent in high-performance Honda engines. If you are performing a timing belt service or building a high-revving B-series engine, replacing the old, stretched factory bolt with this ARP unit is a smart, cost-effective insurance policy for your crankshaft. Don't risk your engine's health with worn-out hardware. Trust the experts at GGCRACING for all your high-performance engine fastener needs.
