Product Details

The ARP 235-2502 is a high-strength harmonic balancer bolt kit engineered to withstand the extreme forces generated by crankshaft flex and twist. Rated at 200,000 psi tensile strength, these bolts provide maximum clamping force to securely lock the harmonic balancer in position under demanding performance conditions.

Key Features:

  • 200,000 psi tensile strength for superior clamping force and reliability
  • 12-point head design accepts deep sockets and prevents stripping
  • 1/4 inch thick wide-area washer distributes load evenly
  • Extra tall head profile ensures proper socket engagement
  • 1/2 inch square drive forged into bolt head for engine rotation with standard ratchet or breaker bar
  • Constructed from heat-treated 8740 chrome moly steel
  • Heavy-duty black oxide finish for corrosion resistance

This square drive harmonic balancer bolt combines the strength needed to secure your balancer with the convenience of rotating the engine assembly using any standard 1/2 inch drive tool. The forged square drive feature eliminates the need for separate crank rotation tools during engine building or maintenance.
