Product Details

The Dayco 89291 No Slack Automatic Belt Tensioner is engineered to resolve common belt-related issues including belt squeal, improper tracking, slippage, and accessory failure. This premium tensioner assembly features Dayco's patented flat spring technology that maintains constant tension throughout the life of your serpentine belt by automatically compensating for stretch and wear.

Key Features:

  • Patented flat spring design provides less operating range variation for consistent belt tension
  • Heavy-duty cast aluminum spring case and arm resist cracking, fatigue, and distortion
  • PTFE string wound within the spring resists abrasion and dampens noise
  • Smooth pulley design with 3-inch outside diameter
  • Premium thermoplastic rubber spring slot plugs and O-ring seals keep contaminants out
  • Zinc-coated mounting bolts resist rust and corrosion
  • Lubricated bearings and high-temperature seals ensure peak performance
  • Steel locator pins and arm plates for enhanced durability

This tensioner reduces the risk of premature accessory bearing failure caused by high tension while preventing belt noise and slippage from low tension. Built to outperform and outlast OEM parts, the Dayco 89291 delivers quieter operation and extended service life even in the toughest under-hood conditions.

Great products and great pricing. Fast shipping. Couldn't ask for anything more. A++++++ merchant. Hope to do business with again.

Quick and easy. Beat all other prices.I'd definitely use them again.

Great to deal with both online and over the phone. Buy with confidence.

Great prices on a great product. Easy to navigate website! will be using them in the future for any additional parts I may need!

This place is excellent. Very easy to use. My parts were shipped on time, and they kept me updated with multiple emails throughout the process. Would definitely buy from these guys again. A++

Good price on my THU-A90275. Had to contact customer service...they were professional and eventually resolved my concern. Called over the phone and the guy told me he couldn't help me with a coupon/refund, but that I had to contact support via email (I guess the phone support and email support aren't one and the same). It took a couple emails, but eventually they refunded me what was due.

I placed an order 12/5/11 and recieved my order before 10am the following day. Very fast, very easy to use and the best prices I've found on line.
