Dayco 5050540 Poly Rib Serpentine Belt - 5-Rib 54 Inch

The Dayco 5050540 is a high-quality poly rib serpentine belt featuring a 5-rib design with a 54-inch length, engineered specifically for passenger cars and light-duty trucks. Built for the high-mileage, demanding drives found in today's vehicles, this belt delivers exceptional performance and durability.

Key Features:

• Innovative W Profile design with a cut into the tip of each rib makes the tip more flexible and eliminates belt chirp when entering worn or misaligned pulleys
• Constructed with aramid-reinforced EPDM compounds that resist cracking and perform better in extreme temperature ranges
• Transverse groove design runs cooler (up to 50° F) and dramatically reduces rib cracking, increasing belt life by at least 40%
• Grooved design provides flexural stress relief for increased flexibility in both normal and backside bending, while being less susceptible to environmental factors such as dust and splash-induced slip
• Cord is saturated with specially formulated treatment that ensures length and tension stability for the life of the belt
• Meets or exceeds SAE J1459 and SAE J2432 specifications

This belt replaces NAPA 25-050538, Goodyear 4050539, Gates K050538, ACDelco 5K538, Bando 5PK1365, Mitsubishi MD195135, MD338462, MD365263, and other OEM part numbers, making it a versatile replacement option for multiple applications.
