Product Details

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 keep the harmonic balancer locked securely in position.

Key Features:

  • 200,000 psi rated bolts manufactured from heat-treated 8740 chrome moly steel
  • Extra tall 12-point head accepts deep sockets and eliminates stripping concerns
  • 1/4 inch thick, wide area washer for optimal load distribution
  • Integrated 1/2 inch square drive forged into bolt head for engine rotation
  • Compatible with standard 1/2 inch drive ratchet or breaker bar
  • Heavy-duty black oxide finish for corrosion resistance

The unique square drive design allows you to rotate the crankshaft assembly using any 1/2 inch drive tool, making engine assembly and timing procedures significantly easier. This professional-grade fastener solution combines the security of a high-strength balancer bolt with the convenience of a built-in crankshaft rotation tool.

The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity
