Product Details

The Dayco 89059 No Slack idler pulley is engineered to maintain proper serpentine belt tension and alignment in automotive accessory drive systems. This precision-manufactured pulley features Dayco's No Slack design, which helps prevent belt slippage and reduces noise from worn or loose belt systems.

Key Features:

  • No Slack design maintains consistent belt tension throughout the service life
  • Precision-machined pulley surface ensures smooth belt operation
  • High-quality bearing assembly for reliable, long-lasting performance
  • Engineered to OEM specifications for proper fit and function
  • Reduces belt squeal and extends serpentine belt life

Dayco idler pulleys are designed to restore proper belt drive operation and eliminate common issues associated with worn pulleys, including belt noise, premature belt wear, and accessory component failure. The sealed bearing design protects against contamination and provides maintenance-free operation.

Very easy and helpful

Good job

Excellent!

I received my part sooner than expected. It was a clone of the factory piece only at a much better price. Quick and easy. No sales tax and it was delivered to the door.

Excellent AAAA++++++

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Easy to use website and service

Super fast shipping, Best pricing that I was able to find on the internet. Will do business with them again and recommend them to my friends.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
