Dayco Gold Label Heavy Duty Serpentine Belt

The Dayco Gold Label Heavy Duty Serpentine Belt (also called a Poly Rib Gold Label drive belt or accessory drive belt) is a diesel-grade replacement belt. It is built for the high torque and power pulses of demanding diesel and high-output gas engines. It drives the alternator, power steering pump, water pump, A/C compressor and other accessories from a single belt.

Key Features:

• Diesel-grade construction: Higher-performance build than conventional light-duty belts, for demanding accessory drives.
• EPDM compounds: Resist heat and the harsh under-hood environment.
• Specially treated cords: Resist stretch and keep belt length stable under high torque and strong power pulses.
• Strength with flexibility: Heavy-duty construction adds integrity without losing the flexibility needed to wrap around small pulleys.
• Ribbed design: Longitudinal ribs help maintain tension and reduce slippage for efficient power transfer.
• Built for tough service: Suited to over-the-road and off-road conditions in personal and commercial use.

Dayco is a long-established name in belts and engine drive components. Gold Label belts are a durable, OE-grade replacement choice for heavy-duty and diesel accessory drive systems. Select the specific belt that matches your application from the variants listed.
