Product Details

The harmonic balancer mounts to the crankshaft hub and helps absorb engine vibration through its dampening layer and outer pulley section. When that dampening material deteriorates, the pulley can move out of alignment and place added stress on the belt drive and crankshaft. ATP Parts 102274 is engineered as a direct OE-style replacement for the 2003-2006 Dodge Sprinter 2500 and 2003-2006 Dodge Sprinter 3500 with a 6-groove serpentine setup. This part cross-references Pioneer Automotive Industries DA-2687 for the same application.

Common Problems This Part Can Address

• Crankshaft vibration from a worn balancer
• Serpentine belt misalignment
• Outer pulley movement caused by deteriorated dampening material
• Noise from a failing harmonic balancer
• Engine damage risk from continued balancer failure

Installation Notes and Tips

Verify crankshaft fitment, groove count, and pulley alignment before installation. Inspect the serpentine belt, belt tensioner, and adjacent pulleys for wear while servicing the balancer. Use the correct service procedure and torque specifications for the engine to help ensure proper crankshaft mounting and belt tracking.

Quality Assurance

ATP Parts OE Replacement Balancer components are built to match original part fit and function, helping restore normal engine operation after a failed harmonic balancer is replaced.
