Product Details

The Dayco 89163 is a high-performance drive belt idler pulley engineered for reliable accessory belt operation in automotive applications. This 80mm diameter serpentine pulley features advanced polymer construction designed to run cooler and last longer than traditional metal pulleys.

Key Features:

  • Glass-filled polymer construction for high strength and maximum wear resistance
  • 80mm diameter with 26mm width accommodates up to 6-rib serpentine belts
  • 10.15mm bearing inner diameter with lifetime lubricated ball bearing
  • Flat profile without flange for precise belt tracking
  • Double high-temperature seals protect bearing from contaminants
  • Engineered with 3-D CAD and finite element analysis for optimal structural integrity
  • Tighter tolerances and smoother surfaces reduce vibration and extend belt life

This OE replacement pulley is designed to meet or exceed original equipment specifications, providing a direct-fit solution for your vehicle's accessory drive system. Each pulley is sold individually and comes backed by Dayco's limited warranty.
