Dayco Poly Rib Gold Label Serpentine Belt

The Dayco Poly Rib Gold Label Serpentine Belt line is a heavy-duty, diesel-grade multi-rib drive belt (also called a serpentine belt, poly-V belt or accessory drive belt). It transfers engine power to accessories such as the alternator, water pump, power steering pump and A/C compressor. Gold Label belts use a higher-performance construction than conventional light-duty belts. They are built for the high torque and power pulses of demanding diesel and gas engines.

Key Features:

• Heavy-duty construction: adds integrity and durability without sacrificing flexibility.
• EPDM compound: high-grade EPDM resists heat and harsh under-hood environments.
• Treated cord reinforcement: specially treated cords resist stretching and keep the belt length stable under high torque loads.
• Multi-rib design: longitudinal ribs help maintain tension and reduce slippage, so accessories are driven reliably.
• Built for demanding service: suited to on-highway, off-road and commercial applications.

Dayco is a long-established name in belt and drive-system products. Gold Label belts give a dependable, OE-grade replacement for heavy-duty accessory drives. Select the child item that matches your drive layout.
