6-Rib Serp. Belt 37.4in

The 6-Rib Serpentine Belt 37.4in by KRC is an essential component for vehicles equipped with a serpentine belt-driven accessory system. This belt plays a crucial role in synchronizing power delivery from the engine to vital auxiliaries such as the alternator, water pump, power steering pump, and air conditioning compressor. A well-functioning serpentine belt is vital for maintaining engine reliability and performance.

Designed with six ribs, this serpentine belt ensures efficient power transfer across multiple pulleys, minimizing slippage under load. Measuring 37.4 inches in circumference, it is suitable for mid-sized engine applications, providing consistent torque to auxiliary drives through precise rib engagement. The engineered rubber compound is resistant to heat degradation, oil contamination, and glazing, which are common failure modes as belts age or operate under improper tension.

Mechanics and automotive enthusiasts trust this KRC serpentine belt for both stock restorations and modified engine builds, especially where upgraded alternators or increased cooling demands are present. Installation is straightforward, requiring only a belt tensioner tool and basic wrench work, making it accessible for both professionals and DIYers alike.
