Dayco A060663 Aramid Cord Poly Rib Serpentine Belt - 6-Rib 66.26

The Dayco A060663 is an aramid cord poly-V serpentine belt engineered to deliver a quiet, vibration-free belt drive system. Designed specifically for higher-output OE engines that demand an aramid belt, this 6-rib, 66.26-inch belt is a direct-fit replacement built to meet or exceed original equipment specifications.

Unlike standard polyester-corded belts, the A060663 uses an aramid tensile cord construction that resists elongation under high accessory loading, providing exceptional length stability. This minimizes span vibrations and reduces excessive tensioner movement — common causes of belt noise and premature wear.

The belt is constructed using Dayco's specially formulated EPDM rubber compound, which resists cracking and maintains performance across a wide range of operating temperatures. It meets SAE J1459 and SAE J2432 industry standards.

Key Features:

• Aramid cord construction resists elongation during high accessory loading
• Length stability reduces span vibrations and excessive tensioner movement
• EPDM rubber compound resists cracking under extreme temperature ranges
• 6-rib profile, 66.26" outside length
• Ideal for NVH (noise, vibration, harshness) applications and drives with minimal tensioner take-up
• Meets SAE J1459 and SAE J2432 standards
• Direct replacement for OEM aramid belt applications

The Dayco A060663 poly rib serpentine belt is the preferred solution for demanding drive systems where standard belts fall short, offering long service life and quiet, reliable operation.
