Dayco Poly-V Ribbed Belt 4PK0865
Dayco® developed the first Polyrib or Multirib belt for the Ford Mustang in the USA in 1979, and this belt continues to set the industry standard today. The 4PK0865 features multiple ribs with a flat design that provides better belt to pulley contact for less slippage than conventional V-belts.
Key Features
- Superior Construction: Built with aramid-reinforced EPDM compounds that exceed Original Equipment (OE) specifications for enhanced durability and performance
- Advanced Design: The grooved design provides flexural stress relief for increased flexibility in both normal and backside bending
- Environmental Resistance: Grooves render the belt less susceptible to environmental factors such as dust and splash-induced slip
- Load Carrying Capability: Dayco's superior manufacturing technology uses rubber-impregnated fabric backing that maximizes load carrying capability
- Noise Reduction: Minimizes noise often associated with competitor belts
- Cord Treatment: The cord is saturated with a specially formulated treatment that ensures length and belt stability for the life of the belt
- Controlled Slippage: Multiple ribs eliminate the need for matching and allow for controlled slippage in overload situations, such as when an A/C compressor engages
