Detailed Product Description

This serpentine belt drive component kit includes two belts: one with an outside circumference of 81.125 inches (2061 mm) and a top width of 0.947 inches (24 mm), and another with an outside circumference of 56.022 inches (1423 mm) and a top width of 0.807 inches (20 mm).
