Product Details

The ARP 120-2501 harmonic balancer bolt kit is engineered to withstand the extreme kinetic energy absorbed by your engine's harmonic balancer as the crankshaft flexes and twists. These ultra-strong bolts are rated at 200,000 psi tensile strength, allowing you to apply maximum clamping force to keep the balancer securely locked in position under demanding conditions.

Key Features:

  • 200,000 psi tensile strength for superior clamping force
  • Constructed from heat-treated 8740 chrome moly steel for exceptional durability
  • Heavy-duty black oxide finish resists corrosion
  • Extra tall 12-point head accepts deep sockets and prevents stripping
  • 1/4 inch thick wide area washer distributes load evenly
  • 1/2 inch square drive forged into bolt head enables engine rotation with any 1/2 inch drive tool
  • Eliminates the need for separate tools when rotating the crankshaft assembly

This square drive design is ideal for engine builders and mechanics who need to rotate the crank assembly during installation, timing, or inspection procedures. Simply use a standard 1/2 inch drive ratchet or breaker bar directly on the bolt head.
