Product Details

The Dayco 89364 No Slack Automatic Belt Tensioner is engineered to maintain proper belt tension throughout the life of your serpentine belt system. This precision-engineered tensioner automatically compensates for belt stretch and wear, ensuring consistent tension and preventing belt slippage that can lead to accessory failure.

Key Features:

  • Automatic tension adjustment eliminates manual belt adjustments
  • No Slack design maintains optimal belt tension under all operating conditions
  • Durable construction with high-quality bearings for extended service life
  • Direct OE replacement for Ford applications
  • Engineered to withstand extreme temperatures and engine vibration
  • Helps prevent premature belt wear and accessory damage

This tensioner is designed as a direct replacement for worn or failed original equipment, restoring proper belt system operation and protecting critical engine accessories like the alternator, power steering pump, and air conditioning compressor. The spring-loaded design automatically maintains proper belt tension as components wear over time.

Thank you

Would buy from again

Great price

Ordered the product on a Friday at about 11am, the product arrived the following Monday at noon from PA, to KS! The shipping was free, no sales tax, and the product was $65.00 less expensive here. Called customer service prior to ordering to verify a couple of things before ordering, and the experience was excellent! This was my first order with Autoplicity, after this, they will be my first shopping stop from now on!

Overall experience was ok. Got my items at a very great price. Cheapest I found online BUT the shipping was a slight nightmare. Had to call multiple times and items finally got to me but other than I am pleased. I ordered a few days before black Friday/cyber Monday deals so that could've been the problem too. In the end I got what I wanted at the best price!

It's was perfect

So far so good

Extremely fast, delivery was sooner than expected

Great price and good company to buy from!

Ordered Borla headers 17216 that was lowest price on internet. Shipped fast at a fair price and arrived in good condition. Communication from Autoplicity was timley and accurate with tracking number. I would not hesitate to order from them again.

Awsome service and prices,Thanks alot

Thankyou so much

By far the best price, easy ordering, and fast service, what else is there?

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!
