84.5 inch serpentine belt

The term 7pk refers to the specification of a serpentine belt. The 7 denotes the number of ribs or grooves that the belt has, while pk indicates that it is a type of poly-V belt, which features multiple ribs running along its length. These ribs enhance grip and allow the belt to transmit power effectively across various pulleys in an engine. The poly-V design aids in reducing friction, which in turn improves fuel efficiency and engine performance.

Furthermore, the rise of electric vehicles (EVs) and hybrid technologies is also influencing the timing belt market. As the automotive industry moves towards more sustainable alternatives, the need for traditional internal combustion engines—and therefore timing belts—may diminish. However, while the shift to electric vehicles is underway, many existing vehicles still rely on timing belts. Thus, the importance of this component cannot be overstated in the current automotive landscape.
