Product Details

The Dayco 89473 No Slack Heavy Duty Automatic Belt Tensioner Assembly is engineered to maintain constant tension on serpentine belt drives in commercial trucks and heavy-duty vehicles. This premium tensioner features Dayco's original flat spring technology designed to provide less operating range variations in tension, compensating for belt stretch and wear throughout the life of your belt.

Key Features:

  • Heavy-duty construction with cast aluminum housing and arm for maximum durability
  • Flat spring technology maintains constant belt tension and increases torque transmission when needed
  • 8-rib serpentine pulley design for heavy-duty applications
  • Steel locator pins and arm plates for reliable performance
  • Resolves common belt issues including squealing, improper tracking, and accessory failure
  • Engineered to outperform and outlast OEM parts

This tensioner assembly is designed for commercial truck applications including Peterbilt, Sterling, Volvo, Western Star, Freightliner, and Kenworth models. It replaces OEM part numbers including Gates 38627, Cummins 3973819, Goodyear 49581, and CNH 87345929.

Everything was as expected.
