Dayco 5060538DR Serpentine Belt 6-Rib 53.8in Heavy-Duty Poly-V Drive Belt

The Dayco 5060538DR is a heavy-duty 6-rib poly-V serpentine belt engineered for reliable power transmission across engine accessory drives. With an effective outside length of approximately 53.8 inches and a standard 6-rib (6PK) profile, this belt delivers consistent performance under demanding operating conditions.

Dayco manufactures this serpentine belt using high-strength EPDM (ethylene propylene diene monomer) rubber compounds, which provide superior resistance to heat, ozone, and cracking compared to traditional neoprene belts. The precision-engineered rib geometry ensures quiet, vibration-free operation and maximum contact with drive pulleys.
