Where the rubber meets the road in testing, research, development and materials science. Dayco has been developing OE quality belts since the early 1970s. And, throughout the years, our scientists and researchers have worked meticulously to invent new belt technologies with unique chemistries and materials for a range of drive system designs and applications. We utilize the highest quality rubber, EPDM, polymer compounds, carbon fibers, aramid and more, so that our belts provide longer lasting performance, excellent temperature resistance, less slippage and reduced noise and vibration. And as our designs continue evolving, we bring to market more coverage and applications across different market segments which meet ever-changing performance and environmental requirements.

The Poly-V belts are produced for auxiliary transmissions of cars, commercial vehicles, heavy duty vehicles and buses. Service belts control almost all auxiliary systems. They have very important functions controlling the correct operation of

• The climate control compressor
• The power steering pump
• In some cases even the water pump
• The alternator
