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.
