Dayco 5080515 Poly Rib Gold Label Serpentine Belt - 8-Rib 51.5 Inch

The Dayco 5080515 is a heavy-duty Poly Cog Gold Label serpentine belt engineered for demanding power transmission applications. This 8-rib belt measures 51.5 inches in length (8PK1310 metric designation) and features advanced diesel-grade construction designed for high torque and power pulses.

Advanced Design Features:

• Transverse cogged design runs up to 50°F cooler than conventional belts and reduces rib cracking for at least 40% longer service life
• EPDM rubber compound provides superior resistance to extreme temperatures, heat, and harsh underhood environments
• Multiple-rib design delivers better belt-to-pulley contact for reduced slippage and extended wear
• Grooved construction provides flexural stress relief for increased flexibility in both normal and backside bending
• Specially treated polyester cord ensures length and tension stability throughout the belt's service life
• Enhanced load-carrying capability with minimized noise compared to standard multi-rib belts

The Gold Label line features more polyester cords per inch than light-duty belts and is built to withstand the demanding conditions of heavy-duty diesel engines and over-the-road applications. This belt meets or exceeds SAE J1459 and SAE J1596 specifications, ensuring reliable performance in commercial vehicles, construction equipment, and heavy-duty automotive applications.
