Product Details

The Proform Parts 66509 is a high-quality replacement harmonic balancer designed specifically for Small Block Chevy 350 engines with internal balance. This essential engine component helps reduce crankshaft vibrations and protect your engine from damaging harmonics during operation.

Key Features:

  • 6-3/4 inch outer diameter for proper Small Block Chevy 350 fitment
  • Designed for internally balanced SBC 350 engines
  • Replaces worn or damaged factory harmonic balancers
  • Precision-manufactured for reliable vibration dampening
  • Direct replacement for stock harmonic balancer applications

This harmonic balancer is a critical component for maintaining engine longevity and smooth operation. The 6-3/4 inch diameter size is the correct specification for Small Block Chevy 350 cubic inch engines that use an internal balance configuration. Proper harmonic dampening helps prevent crankshaft fatigue and extends engine life.
