Dayco No Slack Idler Tensioner Pulley

The Dayco No Slack Idler/Tensioner Pulley is a replacement drive belt idler pulley and tensioner pulley. It is designed to replace worn serpentine and V-belt drive idler and tensioner pulleys. Dayco engineers the line to keep the belt drive running smoothly and to help the belt last longer.

Key Features:

• Precision manufacturing: Smoother surfaces and tighter dimensional tolerances reduce vibration and help extend belt life.
• Engineered design: 3D computer-aided design (CAD) and finite element analysis (FEA) are used to build in structural integrity.
• Quality bearings and seals: Lubricated bearings and high-temperature seals support bearing performance. The bearing is the most critical element of a pulley's service life.
• Material options: The line includes steel pulleys and pulleys made from glass-filled polymer, a strong, wear-resistant plastic. Steel pulleys may have a corrosion-resistant e-coating.
• OE-quality replacement: Built to meet or exceed OEM specifications.
