Product Details

The Dayco 89380 No Slack Automatic Belt Tensioner Assembly is engineered to maintain constant tension on serpentine belt drives for optimal engine accessory performance. This heavy-duty tensioner features Dayco's patented flat spring design that provides less operating range variation, reducing the risk of premature accessory bearing failure and belt noise while preventing slippage caused by improper tension.

Key Features:

  • Heavy-duty cast aluminum spring case and arm for superior strength and resistance to cracking and fatigue
  • PTFE string wound within the spring to resist abrasion and dampen noise
  • Lifetime lubricated bearings and high-temperature seals for peak performance
  • Premium thermoplastic rubber spring slot plugs and O-ring seals keep contaminants out
  • Smoother surfaces and tighter dimensional tolerances to extend belt life
  • Zinc-coated mounting bolts resist rust and corrosion
  • Steel pivot tube on specific designs for enhanced stability

This exact OE replacement tensioner assembly is designed to reduce wear, friction, vibration, and harshness while assisting critical engine accessories including air conditioning compressors, alternators, power steering pumps, and water pumps. Built to withstand dirt, salt, chemicals, and harsh under-hood conditions, the Dayco 89380 delivers reliable, long-lasting performance.

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Best price I could find on the net and super fast shipping.

Autoplicity had the best price on the VP fuel jugs, I ask if the could ship them out quickly and they did.

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

i was skeptical about this site but after reading the reviews and them having the lowest price i could find for my part i pulled the trigger and wasn't disappointed. fast shipping and low prices with great customer service will shop with them again if they have what im looking for.

I placed an order,18852,for a Husky Liner on June 19th and received it on June 21st. They have a great price and low cost shipping.

Quick shipping, good communication, low price, would purchase again from this company.
