Race Performance Harmonic Balancer

Dayco PB1009SS is a race performance harmonic balancer built for classic Ford and Mercury V8 applications that require a 3-bolt, hub-weighted design. It features a steel outer ring, timing marks, and a 6.497-inch overall outside diameter for performance-focused engine builds.

Compatible With Ford Mustang, Mercury Cougar, Ford LTD, Mercury Montego, and related full-size and intermediate applications listed below, this balancer is a direct-fit option for engines that use the specified crank bore and nose dimensions. The PB1009SS part number is also referenced for the same application under Pioneer 872029.

Key Features

  • Hub-weighted harmonic balancer for race performance use
  • Steel outer ring for durable rotating assembly construction
  • Timing marks included for engine setup and service
  • 3-bolt configuration with no integrated pulleys
  • Crank bore measures 1.375 inches (34.90 mm)
  • Overall outside diameter measures 6.497 inches (165.00 mm)

Detailed Description

The Dayco Race Performance Balancer line is aimed at performance engine combinations that need a harmonic balancer with race-oriented construction and accurate timing reference points. PB1009SS uses a hub-weighted counterbalance, a steel outer ring, and a 3-bolt layout, making it suitable for older Ford and Mercury engines listed in the fitment data. The PB1009SS part number appears across applications such as 1969-1974 Ford LTD, 1970-1973 Ford Mustang, and 1969-1974 Mercury Montego.

Fitment includes 1969-1974 Ford LTD, N/A; 1970-1973 Ford Mustang, N/A; 1969-1974 Mercury Montego, N/A; 1969-1974 Mercury Cougar, N/A; and 1975-1980 Ford E-Series van and Club Wagon applications with the notes shown in the fitment table. Use the listed notes to confirm Electronic Engine Control and counterweight requirements before ordering.

What This Part Helps Address

  • Crankshaft vibration control in performance engine builds
  • Timing reference visibility during ignition setup
  • Replacement needs for 3-bolt balancer applications
  • Fitment requirements for engines without Electronic Engine Control
  • Counterweight and pulley configuration matching on listed classic applications

Installation Notes and Tips

Confirm crank bore, nose diameter, and bolt-hole pattern before installation. This balancer does not include hardware, installation instructions, a crank trigger/exciter plate, or a woodruff key. Review the fitment notes carefully for vehicles that require w/o EEC or specific counterweight and countersunk pulley configurations.

Quality Assurance

Dayco’s Race Performance Balancer line is built for performance-oriented engine applications and uses a steel outer ring with integrated timing marks for service accuracy. Cross-reference: this part cross-references Pioneer 872029 for the same application.
