Caliso 315K5 Poly V Serpentine Belt - 5-Rib 31.5

The Caliso 315K5 is a K-section Poly V (Multi-V) serpentine belt featuring 5 ribs and an outside circumference of approximately 32.25 inches with a pitch length of 31.5 inches. Designed for high-speed accessory drive applications, this belt delivers reliable power transmission to engine-driven components such as the alternator, power steering pump, and air conditioning compressor.

Constructed from abrasion and heat-resistant rubber compound, the 315K5 is built to withstand the demanding thermal and mechanical stresses of modern automotive drive systems.
