Caliso 436K6 Poly V Serpentine Belt K-Section - 6-Rib 43.6in

The Caliso 436K6 is a K-Section Poly V (serpentine) belt featuring 6 ribs and a 43.6-inch pitch length. Also known as a Micro-V or Multi-Rib belt, this FVP-labeled drive belt is engineered to meet or exceed OEM specifications for reliable power transmission across engine accessory drive systems.

Constructed from heat and ozone resistant EPDM rubber, the 436K6 is built to withstand the demands of modern automotive and powersports drive systems. Fiber reinforcement is integrated into the rib stock to reduce noise and maintain performance even with worn or slightly misaligned pulleys. A treated polyester tensile cord resists belt stretch and helps maintain consistent tension over the belt's service life.
