Damp crankshaft torsional vibration and keep the accessory belt tracking true with the Pioneer Automotive Industries Engine Harmonic Balancer DA-3021. It's an OE-design replacement for a long list of 1975-1998 Ford, Lincoln and Mercury applications — including the Ford Bronco, F-150, F-250, Mustang and Thunderbird, the Lincoln Town Car and the Mercury Grand Marquis and Cougar — with the L6-4.9L, V8-4.2L, V8-5.0L or V8-5.8L engine. See the Buyer's Guide tab for the full list of 44 applications.
- Developed to the OE design: built to the original design so it installs properly and functions as intended.
- Quality materials: made from high-grade metals and rubber that are bonded or pressed to the original specifications.
- Precision-built: each component is precision machined and the assembly is dynamically balanced.
A harmonic balancer mounts to the front of the crankshaft, where its bonded rubber element helps absorb the torsional vibration created as the crankshaft rotates, and its hub typically drives the accessory belt. Signs the original may need replacing include noticeable engine vibration, a cracked or separated rubber ring, or a wobbling balancer. If a worn balancer is the cause, this unit replaces it — diagnose the condition first.
