Dayco A060855 Aramid Cord Poly Rib Serpentine Belt - 6-Rib 85.5in

The Dayco A060855 is an aramid cord Poly Rib serpentine belt engineered for high-output OE engine applications that specifically require an aramid-reinforced drive belt. Measuring 85.50 inches in free length with a 0.82-inch top width and 6 ribs (metric equivalent: 6PK2170, W Profile), this belt is a direct-fit replacement for vehicles where standard polyester-corded belts are insufficient.

Key Features:

• Aramid cord construction resists elongation under high accessory loading, maintaining precise length stability throughout the belt's service life
• EPDM rubber compound specially formulated by Dayco to resist cracking and deliver reliable performance across extreme temperature ranges
• W-profile rib design runs cooler and quieter, reducing noise from slippage and minimizing span vibrations
• Minimal stretch design aids in drive systems where tensioner take-up is limited or tensioner movement is excessive
• Engineered for NVH reduction — ideal for applications experiencing noise, vibration, or harshness (NVH) issues in the accessory drive system
• Meets or exceeds OEM specifications for applications requiring an aramid serpentine belt

Unlike standard polyester-corded serpentine belts, the Dayco A060855 is purpose-built for higher-demand drives where length stability is critical. The aramid cord reinforcement maintains consistent tension, helping to protect accessory components such as the alternator, power steering pump, air conditioning compressor, and water pump from the stress of belt slippage or inconsistent drive engagement.
