Dayco is an American company operating on a global scale, specializing in the development, production, and distribution of essential engine and transmission systems. Its product range includes timing belts, multi-rib belts, tensioners, dampers, pulleys, and hydraulic hoses. The company traces its origins back to 1905, when it was founded as the Dayton Rubber Manufacturing Company in Dayton, Ohio, by Colonel J.C. Hooven. Initially, it produced garden hoses and rubber seals for canning jars.

In 1960, the company changed its name to DAYCO Corporation, highlighting its broad ambitions within the industry. A major milestone occurred in 1993, when Dayco acquired the industrial transmission division of Pirelli (PTI Spa), including the Isoran brand. This move significantly strengthened Dayco’s position in the power transmission market.

Today, Dayco is headquartered in Birmingham, Michigan, and has a global presence with over 50 locations in 18 countries. The company is known for its continuous investments in innovation and quality, consistently adapting to the evolving needs of the market. The rise of hybrid and electric vehicles also plays an important role in the ongoing development of its product portfolio.
