K Series Serpentine Belts – High-Performance Multi-Rib Belts for Automotive and Industrial Applications
K Series serpentine belts, also known as K-section Poly-V belts, are engineered to deliver exceptional power transmission in compact, high-speed, and high-torque drive systems. With their multi-ribbed, low-profile design and superior flexibility, these belts provide smooth, quiet, and efficient operation across a wide range of automotive, industrial, and commercial machinery. Their 3.56 mm rib pitch ensures excellent pulley engagement and reduced slip, making them a trusted choice for modern serpentine drive configurations.
