Dayco 5071040 Poly Rib Serpentine Belt - 7-Rib 104 Inch

The Dayco 5071040 is a high-performance poly rib serpentine belt engineered with advanced poly cog technology for demanding automotive and light truck applications. This 7-rib belt features a 104-inch pitch length and 0.98-inch width, designed to deliver superior performance in accessory drive systems powering components like alternators, water pumps, power steering pumps, and air conditioning compressors.

Key Features:

• Aramid-reinforced EPDM compound construction resists cracking and performs better in extreme temperature ranges
• Transverse groove poly cog design runs up to 50°F cooler than conventional belts
• Grooved backside provides flexural stress relief for increased flexibility in both normal and backside bending
• Specially treated cords ensure length and tension stability throughout belt life
• Superior rubber backing maximizes load-carrying capability while minimizing noise
• Meets or exceeds SAE J1459 and SAE J2432 specifications
• 7 ribs for optimal power transfer and reduced slippage

Dayco's poly cog design dramatically reduces rib cracking and increases belt life by at least 40% compared to conventional multi-rib belts. The unique grooved construction allows controlled slippage during shock load situations while maintaining excellent torque-carrying capacity. As the manufacturer of the first original equipment multi-ribbed serpentine belt, Dayco continues to deliver industry-leading quality and innovation.
