Dayco 89208 No Slack Automatic Belt Tensioner Assembly

The Dayco 89208 No Slack Automatic Belt Tensioner is engineered to maintain consistent tension on serpentine belt drives throughout the life of your belt. This automatic tensioner features Dayco's innovative flat spring design that provides reduced operating range variations in tension, helping to eliminate common belt problems like squealing, improper tracking, and accessory failure.

Key Features:

• Patented flat spring design maintains constant tension and compensates for belt stretch and wear
• Cast aluminum housing and arm construction for superior durability and resistance to cracking
• Steel locator pins and arm plates engineered to withstand extreme drive demands
• PTFE strip wound within the spring resists abrasion and extends service life
• Rust-resistant coated flat spring for long-lasting performance
• Reduces risk of premature accessory bearing failure from excessive tension
• Minimizes belt noise, slippage, and poor accessory performance caused by low tension

Designed to meet or exceed OEM specifications, the Dayco No Slack tensioner helps ensure optimal performance of all engine accessories powered by the serpentine belt system. The advanced flat spring technology allows torque to be transmitted when needed while preventing the tension-related issues common with traditional tensioners.
