Product Details

The Dayco 89663 No Slack automatic belt tensioner assembly is designed to resolve common serpentine belt issues including belt squeal, improper tracking, and accessory component failures. This high-quality tensioner features Dayco's patented flat spring technology that automatically adjusts to compensate for belt stretch and wear while maintaining constant tension throughout the life of your serpentine belt.

Key Features:

  • Flat spring technology provides consistent torque transmission and maintains proper belt tension
  • Heavy-duty cast aluminum housing and arm resist cracking and fatigue
  • Steel locator pins and arm plates for precise installation and durability
  • Smooth pulley design for reliable operation
  • Engineered to outperform and outlast OEM components
  • Sold individually as a complete tensioner assembly

This replacement tensioner is designed for automotive and light truck applications with serpentine belt drive systems. The robust construction and precision engineering ensure long service life and quieter operation compared to worn factory tensioners.

Found part easily.

So far so good...

easy shopping, I have my truck in the shop and waiting for the part

Good price

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

There was no description with my item but the part number is correct so I'm optimistic.

good

very easy

I receive exactly what I ordered on time with no problems… got the best price and service. What else do you need to know! Shop Autoplicity…
