Dayco 5080993 Poly Cog Gold Label Serpentine Belt - 8-Rib 99.25 Inch

The Dayco 5080993 Poly Cog Gold Label serpentine belt is a heavy-duty, multi-ribbed accessory drive belt engineered for demanding diesel and high-output gasoline engine applications. This 8-rib belt measures 99.25 inches in length and delivers superior performance in both passenger vehicles and commercial trucks.

Gold Label Heavy-Duty Construction:

The Dayco Gold Label serpentine belt features higher performance construction over conventional light duty belts to meet the high torque and power pulses exerted by demanding diesel engines. This diesel engine grade belt features more polyester cords per inch than conventional Poly Cog belts, ensuring maximum power transfer and exceptional length stability throughout the belt's service life.

Advanced Poly Cog Design:

• Transverse groove design runs cooler (up to 50° F) and dramatically reduces rib cracking, increasing belt life by at least 40%
• Computer-designed cog placement eliminates harmonic squeal
• Grooved design provides flexural stress relief for increased flexibility in both normal and backside bending
• Straight rib profile offers less noise when running and provides less slippage

Premium Materials and Performance:

• Constructed with aramid-reinforced EPDM compounds that resist cracking and perform better in extreme temperature ranges
• Specially treated cords resist stretching and ensure length stability essential for correct tensioning
• Working temperature range: -45°F to +212°F
• Meets SAE J1459 and J2432 standards
• K-section cross-section design

The high-grade engineered polymer construction is specifically compounded to resist heat and harsh under-hood environments experienced in over-the-road and off-road conditions. This belt provides reliable power transmission to accessory components including alternators, water pumps, power steering pumps, and air conditioning compressors.
