84.5 inch serpentine belt

V-belts have a distinctive trapezoidal cross-section that enables them to fit snugly into the grooves of pulleys. This design allows for efficient power transfer and minimizes the risk of slipping. Typically made from durable materials such as rubber, polyester, and fiberglass, V-belts can withstand a wide range of temperatures, loads, and stretching. The layered construction of a V-belt often includes a tensile cord to enhance its strength and resistance to wear, ensuring longevity in challenging conditions.
