Dayco Poly-V Belt 4PK0815
Industry Leading Design
Dayco developed the first Polyrib or Multirib belt for the Ford Mustang in the USA in 1979, setting the industry standard that continues today. This innovative design features multiple ribs and a flat profile that delivers better belt-to-pulley contact compared to conventional V-belts, resulting in reduced slippage and improved performance.
Key Features
- Multiple Rib Design: Eliminates the need for belt matching and allows for controlled slippage in overload situations, such as when an A/C compressor engages
- 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
- Superior Manufacturing: Features rubber impregnated fabric backing that maximizes load carrying capability and minimizes noise
- High-Grade EPDM Compounds: Engineered to resist heat and harsh under-hood environments
- OEM Specifications: Manufactured to meet original equipment specifications
Technical Specifications
- Ribs: 4
- Outside Length: 32.75 inches (831.85mm)
- Belt Width: 0.56 inches (14.2mm)
- Pitch Length: 32.01 inches (813mm)
Quality & Performance
This belt features a transverse groove design that helps run cooler, reduces rib cracking, and provides enhanced flexibility. Dayco's superior manufacturing technology ensures maximum load carrying capability while minimizing operational noise commonly associated with competitor belts.
The Poly-V belt is designed for automotive power transmission applications and is built to withstand extreme operating conditions while maintaining consistent performance.
