Heavy duty serpentine belts are typically constructed from durable rubber with additional reinforcement. They often contain polyester cord for improved strength and flexibility, as well as a fabric cover to reduce noise and improve resistance to environmental factors, such as oil and heat. Some are further enhanced with special materials to provide better abrasion resistance and longevity, making them ideal for heavy-duty applications in trucks, construction equipment, and commercial vehicles.

A poly V belt, also known as a serpentine belt, is characterized by its multiple longitudinal ribs that provide increased surface contact and improved grip compared to traditional flat belts. The “135J6” designation denotes the specific dimensions and specifications of the belt. In this case, “135” refers to the belt’s length, while “J6” indicates the width and configuration. The poly V belt is designed to fit into a pulley system and is often used to drive multiple accessories in engines, including alternators, power steering pumps, and air conditioning compressors.
