Dayco 5030250DR Poly Cog Serpentine Belt - 25 Inch 3-Rib

The Dayco 5030250DR is a 25-inch long, 0.40-inch wide Poly Cog serpentine belt featuring three ribs designed for reliable power transmission on multiple-accessory drives. This Drive Rite series belt combines the proven multi-ribbed design with advanced cogged technology for superior performance.

Key Features:

• 3-rib micro-V design with 0.42-inch belt width for improved pulley contact
• 25-inch pitch length (25.75-inch outside circumference)
• Transverse grooved design runs cooler and reduces noise from slippage
• Engineered to perform better under overload situations
• Grooved construction runs up to 50°F cooler and increases belt life by at least 40%
• Meets or exceeds SAE J1459 and J1596 specifications

The Poly Cog construction provides flexural stress relief for enhanced flexibility in both normal and backside bending applications. The cord is saturated with specially formulated treatment that ensures length and tension stability for the life of the belt, while the rubber backing maximizes load-carrying capability and minimizes operational noise.
