Product Details

Dayco PB1084SS is part of the Race Performance Balancer line, a product line focused on performance-oriented engine balancing and timing accuracy. This harmonic balancer is built for select Ford Bronco, Mustang, F-150, F-250, Thunderbird, LTD, and related Lincoln and Mercury applications across 1981-1995 model years, including many 1984-1995 Ford Bronco and 1982-1995 Ford Mustang applications. It is also used in select Lincoln Mark VII, Town Car, and Continental models, as well as Mercury Cougar, Grand Marquis, Colony Park, Capri, and Zephyr applications.

This part cross-references ATP 102287 and Dorman 594-024R for the same application. The PB1084SS part number is also commonly referenced when sourcing a replacement engine harmonic balancer for Ford and Lincoln performance and service builds.

Common Uses

• Restoring crankshaft vibration control on a worn harmonic balancer
• Replacing a balancer with damaged timing marks
• Addressing belt drive or front-engine service issues tied to balancer wear
• Supporting engine rebuilds that require correct crank bore and nose dimensions
• Maintaining timing reference accuracy on Ford and Lincoln V8 applications

Installation Notes

Verify crank bore, nose diameter, bolt hole count, and overall dimensions before installation. Because hardware, installation instructions, and a woodruff key are not included, confirm that the required mounting components and engine-specific setup parts are on hand before beginning service. Use the timing marks during final engine setup and follow the vehicle service procedure for balancer installation and torque specifications.

Quality Assurance

Dayco’s Race Performance Balancer line is built for performance-focused engine applications where dimensional accuracy and timing reference matter. PB1084SS is specified with steel outer-ring construction and ring-weighted balance for consistent harmonic control in the listed Ford, Lincoln, and Mercury applications.
