Fits Chrysler 5.7L and 6.1L Hemi engines. This ARP 147-2501 Harmonic Balancer Bolt Kit is designed to provide reliable clamping force for the crankshaft vibration damper, replacing standard factory hardware. Whether you are performing a cam swap or a complete engine rebuild, this 12-point fastener ensures your balancer remains securely seated under high-load conditions.

The 12-point head design provides more contact area for your socket, significantly reducing the risk of rounding the bolt head during high-torque installation or removal. This kit is a direct replacement for OE hardware and includes a thick, wide-area washer to distribute the load evenly across the balancer hub.

  • Manufacturer Part Number: 147-2501
  • Application: Chrysler Hemi 5.7L and 6.1L engines
  • Head Style: 12-Point
  • Includes precision-machined balancer bolt and wide-area washer
  • Engineered for high-performance harmonic balancer retention
