Caliso 445K6 Poly V Serpentine Belt K-Section Pitch - 6-Rib 44.5

The Caliso 445K6 is a K-section Poly V (multi-rib) serpentine belt engineered to deliver reliable power transfer across automotive and powersports drive systems. With 6 ribs and a pitch length of 44.5 inches (outside circumference 45.25 inches), this belt meets the dimensional standard also referenced as 6PK1130 in metric sizing, and crosses over to popular OEM part numbers including K060445, 4060445, and 5060445.

The truncated rib profile maximizes flexibility, reduces heat buildup, and improves traction within sheave grooves while resisting debris contamination. The helically wound polyester tensile cords are heat-set and chemically treated to minimize stretch and ensure consistent tension over the life of the belt. This serpentine belt is well-suited for high-speed, high drive-ratio applications requiring smooth, vibration-free operation.
