Dayco 4PK950EE Poly Rib Stretch Serpentine Belt 4-Rib 37.4in

The Dayco 4PK950EE is a Poly Rib stretch-fit serpentine belt featuring a 4-rib profile and 950mm (37.4 in.) effective length. Designed using Dayco's elastic belt (EE) technology, this belt installs without removing the tensioner — a zip tie is used to hold the belt compressed during installation, making it ideal for tight engine bays and professional shop efficiency.

Built with aramid-reinforced EPDM rubber compounds, the 4PK950EE resists cracking and delivers reliable performance across extreme temperature ranges. The precision-engineered rib profile is designed to conform to high-mileage, worn, or slightly misaligned drive systems, reducing noise and extending service life compared to conventional belts.
