Dayco Poly-V Belt 6PK2565

Industry-Leading Performance

Dayco developed the first Poly-V Belt® (also known as Multirib belt) for the Ford Mustang in the USA in 1979, setting the industry standard that continues today. This revolutionary design features multiple ribs and a flat profile that provides superior belt-to-pulley contact compared to conventional V-belts, resulting in significantly reduced slippage.

Advanced Engineering Features

Multi-Rib Design Benefits:

Eliminates the need for belt matching
Allows controlled slippage in overload situations (such as A/C compressor engagement)
Provides better grip on pulleys with less slipping
Resistant to dust and splash-induced slip

Superior Construction:

Grooved Design: Provides flexural stress relief for increased flexibility in both normal and backside bending
EPDM Rubber Compounds: Built to resist heat and harsh under-hood environments
Rubber Impregnated Fabric Backing: Maximizes load carrying capability while minimizing noise
Specially Treated Cords: Saturated with formulated treatment ensuring length stability and belt longevity
Aramid Reinforced Construction: Exceeds Original Equipment (OE) specifications

Heavy-Duty Performance

This serpentine belt features diesel-grade construction with higher performance engineering designed to meet the high torque and power pulses of today's demanding engines. The specially treated cords resist stretching and ensure length stability essential for modern drive systems.
