This is the "cogged" version of the revolutionary multi-ribbed belt first
developed by Dayco for the 1979 Ford® Mustang®. The
multiple-rib design provides better belt-to-pulley contact for less slippage, so it lasts longer than conventional V-belts. Multiple ribs also eliminate the need for matching, and allows controlled slippage in shock overload situations, such as when the AC compressor kicks in. Today,
as then, this belt sets the industry standard. The transverse groove
design runs cooler (up to 50°F), and dramatically reduces rib cracking, thereby
increasing the life of the belt by at least 40%. The grooved design provides
flexural stress relief, for increased flexibility in both normal and backside
bending. The grooves also render the belt less susceptible to environmental
factors such as dust and splash-induced slip. Dayco's
superior manufacturing technology uses a rubber backing that maximizes
load-carrying capability and minimizes the noise that is often associated with
the competition's belts. Torque-carrying capacity equals or betters
conventional multi-rib belts. The cord is saturated with a specially formulated
treatment that insures length and tension stability for the life of the belt. Dayco Poly Cog belts meet or exceed SAE J1459 and J1596
