About Dayco

Dayco got its start in 1905 in Dayton, Ohio as the Dayton Rubber Manufacturing Company. More than a century later it is headquartered in Birmingham, Michigan and builds engine drive and cooling-system parts for vehicle makers and the aftermarket. Belts, tensioners, pulleys, water pumps and hoses are what the brand is known for, and that is what we stock.

We stock Dayco parts for the accessory drive and cooling system on diesel pickups:

  • Poly Rib and HD Poly Rib serpentine belts, main drive and A/C, including dual-alternator belts for Cummins and Powerstroke trucks
  • Automatic serpentine belt tensioners and idler pulleys
  • Serpentine belt kits with belt, tensioner and idler pulleys
  • DP-series water pumps
  • Curved upper and lower radiator hoses
  • Molded heater hoses and 90-degree coolant hoses
