Collection: A/4L Kevlar
4L/A section Kevlar (aramid) v-belts are high performance belts designed for heavy duty applications requiring superior strength and durability.
Reinforced with aramid fiber cords, these belts offer excellent resistance to stretching, heat, and abrasion, making them ideal for high torque and shock load environments.
Their 1/2" top width and 5/16" depth fit standard A/4L pulleys, commonly used in lawn mowers, snow blowers, and industrial machinery. Kevlar belts also provide longer service life and reduced maintenance compared to standard polyester corded belts.
