Direct Replacement Harmonic Balancer for Mustang

This Dorman harmonic balancer is a direct replacement for select Ford applications and is built to help manage engine vibration at the crankshaft. It is engineered with a stress-resistant rubber bond and ductile steel construction for dependable durability in daily driving and repair work.

  • Direct replacement harmonic balancer for OE-style fitment
  • Stress-resistant rubber bond helps absorb engine vibration
  • Ductile steel construction for tensile and impact strength
  • 6-groove design for serpentine belt systems
  • Black finish with degree markings for timing reference
  • Keyway design and single mounting hole configuration

Fitment and Application

Compatible with 1999-2000 Ford Mustang, N/A. This Dorman 594-740 is a fitment-based replacement for Mustang models that use a serpentine drive belt setup and a keyed harmonic balancer design. It also cross-references Ford XR3Z6B321AA and PowerBond by Dayco PB1831N for the same application.

Product Details

The Dorman 594-740 harmonic balancer is built around a rubber isolator that helps reduce crankshaft vibration while supporting stable engine operation. Its ductile steel body adds strength where the balancer is exposed to repeated load and rotational stress. The 194 mm outside diameter, 35.08 inside diameter, 52.3 depth, and 47.7 mm mounting hole diameter provide the dimensional details needed for accurate replacement selection on the listed Ford Mustang applications.

What It Helps Address

  • Crankshaft vibration transmitted through the engine
  • Worn or deteriorated balancer rubber bond
  • Timing reference visibility with degree markings
  • Replacement needs for a keyed serpentine-belt harmonic balancer
  • Fitment issues caused by incorrect diameter or groove count

Installation Notes and Tips

Verify pulley groove count, inside diameter, outside diameter, and mounting dimensions before installation. Confirm the keyed design, degree markings, and serpentine belt routing match the original part on your Ford Mustang. Inspect the crankshaft snout, keyway, and surrounding components for wear before installing the replacement balancer.

Quality Assurance

Dorman manufactures this harmonic balancer as a direct replacement component using ductile steel construction and a vibration-absorbing rubber bond. The part is built to meet the dimensional and functional requirements of the listed 1999-2000 Ford Mustang applications.
