Product Details

The Dayco 84063 No Slack automatic timing belt tensioner is designed to maintain precise, constant tension on timing belt systems, ensuring optimal engine performance and reliability. This precision-engineered tensioner features Dayco's patented flat spring technology that provides consistent operating range with minimal tension variations throughout the belt's service life.

Key Features:

  • Patented flat spring design reduces tension fluctuations and extends component life
  • PTFE-infused spring construction resists abrasion and wear
  • Rust-resistant coating protects against corrosion in harsh engine environments
  • Precision-engineered to meet or exceed OEM specifications
  • Reduces risk of premature bearing failure and belt slippage
  • Cast aluminum construction for durability and heat dissipation

The innovative No Slack design maintains optimal tension when a new belt is installed, preventing excessive stress on accessory bearings, while continuing to provide proper tension as the belt stretches and wears over time. This helps eliminate belt noise, prevents slippage, and ensures consistent accessory performance. Built with quality materials and backed by Dayco's reputation for excellence, this tensioner is an essential component for timing belt system maintenance and replacement.

I had a great experience shopping at autoplicity

Great price found for my product. excellent customer service and my item was in stock.

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Shipped very quickly and had the best price I could find!

Great experience! I placed my order on Sunday and my programmer arrived on Thursday - with ground shipping. I unpacked the programmer and it functioned exactly as I had hoped. I will definitely consider purchasing from Autoplicity again!

first order fast shipping and great fit

Please for this item, specify that it is only 1 single shock, I was confused. But that yall!

The whole process was some and quick. They also had the lowest prices available. Will be using them more often for sure!!

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.
