Key Features:

• Durable construction: The line includes spun steel pulleys and pulleys made from glass-filled polymer. The polymer is formulated for high strength and wear resistance.
• Engineered for strength: Computer-aided design (CAD) and finite element analysis (FEA) are used to optimize the design and structural integrity of both plastic and steel pulleys.
• Smooth, precise surfaces: Smoother surfaces and tighter dimensional tolerances reduce vibration and extend belt life.
• Quality bearings: Lifetime-lubricated bearings and high-temperature seals help the bearings perform well over time.
• OE-level quality: Designed to meet or exceed OEM specifications for a dependable replacement.

A worn tensioner or idler pulley can cause belt noise, slippage, uneven belt wear and accessory problems. Replacing it with a Dayco No Slack pulley helps restore proper belt system operation. Choose the child item that matches your application.
