Product Details

The Dayco 89252 No Slack Automatic Belt Tensioner is engineered to maintain constant tension on serpentine belt drives, resolving common issues like belt squeal, improper tracking, and accessory failure. This premium tensioner features Dayco's patented flat spring technology that automatically compensates for belt stretch and wear while maintaining consistent tension throughout the belt's service life.

Key Features:

  • Patented flat spring design provides less operating range variation and consistent tension
  • Heavy-duty cast aluminum spring case and tensioner arm resists cracking, fatigue, and distortion
  • Steel locator pins and arm plates for enhanced durability and stability
  • PTFE string wound within spring resists abrasion and dampens noise
  • Premium thermoplastic rubber spring slot plugs and O-ring seals keep contaminants out
  • Zinc-coated mounting bolts resist rust and corrosion
  • Single pulley design with 2.75-inch outside diameter and 6 grooves
  • Lubricated bearings in rugged pulley for long service life

This tensioner assembly is designed to outperform and outlast OEM parts, making it ideal for automotive and light truck accessory drive applications. The advanced damping design uses a wave spring and metal ring with bonded rubber surface to act as a radial shock absorber, reducing vibration and extending component life. Replaces Ford OEM part numbers 1L5E-6B209-AB, 1L5E-6B209-AC, and 1L5E-6B209-AD.

1st time Autoplicity customer and I was very pleased. Will definitely buy from again.

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!

easy web service

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.

Product was as described. Came very quickly...thanks.

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.
