Dayco 5080730 Gold Label Poly Cog Serpentine Belt - 8-Rib 73 Inch

The Dayco 5080730 Gold Label Poly Cog Belt is an 8-rib serpentine belt engineered for heavy-duty diesel engine accessory drives. This professional-grade belt features a 73-inch effective length and is designed to handle the higher torque and power pulses exerted by modern diesel engines in automotive, commercial vehicle, and heavy-duty applications.

Advanced Poly Cog Design:

• Transverse groove design runs up to 50°F cooler and reduces rib cracking for 40% longer belt life
• Computer-designed cog placement eliminates harmonic squeal and vibration
• Grooved construction provides superior flexural stress relief for improved flexibility in both normal and backside bending
• Heavy-duty construction maintains integrity without sacrificing belt-to-pulley compatibility

Premium Materials and Construction:

• Aramid-reinforced EPDM (Ethylene-Propylene-Diene-Monomer) compound resists heat and harsh under-hood environments
• More polyester cords per inch than conventional poly cog belts for enhanced torque capacity
• Specially treated cords resist stretching and ensure length stability for proper tensioning
• K-section profile with 1.10-inch top width
• Temperature range: -45°F to 212°F
• Maximum operating pressure: 50 PSI

Quality and Performance:

• Meets or exceeds SAE J1459, SAE J1596, and SAE J2432 specifications
• Superior rubber backing maximizes load-carrying capability while minimizing noise
• Torque-carrying capacity equals or exceeds conventional multi-rib belts
• Outside circumference: 73.66 inches (1870.97mm)
• Metric equivalent: 8PK1855

Designed for over-the-road and off-road diesel applications, this Gold Label Poly Cog belt delivers the durability and performance required for demanding accessory drive systems.
