Dayco ® Top Cog ® Belt is the workhorse of the heavy-duty industry. The cogs in the top of the belt deliver increased flexibility around small pulleys, and the increased surface area results in a cooler running belt. Polyester cord provides maximum power transfer and tension holding capability for the life of the belt. The laminated construction helps absorb greater shock loads associated with diesel engines. These Dayco ® Top Cog ® advantages translate into less downtime, lower maintenance costs, and increased dependability. The Dayco ® Top Cog ® Belt meets or exceeds SAE J636 and J637 specifications.
