Supercharger Belt Cadillac CTS-V 2009

The DAYCO PRODUCTS LLC Supercharger Belt for Cadillac CTS-V 2009 (part number 5080660SC) is a precision serpentine drive belt engineered to transfer power from the engine's crankshaft to the supercharger in high-performance applications. This 66-inch, 8-rib belt is OEM-spec for 2009–2014 Cadillac CTS-V models and delivers the reliable belt tension and durability that forced-induction engines demand. Supercharger belt performance directly impacts boost delivery and engine efficiency—undersized or worn belts slip under load, reducing boost pressure and power output.

The 8-rib design maximizes contact surface area with the pulley system, ensuring consistent grip across the full operating range of the supercharger. At 66 inches in length, this belt matches the precise circumference required for the CTS-V's LSA engine package, preventing slack and belt noise that would indicate improper fitment. DAYCO is an OEM supplier to major automotive manufacturers, meaning this belt meets the same durability and material standards as factory-installed components. For owners running stock or lightly modified CTS-V supercharger systems, this is a direct replacement that restores original performance and eliminates the risk of belt-related boost loss or engine damage from slipping drives.

Supercharger belt replacement is essential maintenance for any forced-induction engine. Whether you're addressing wear on an existing belt or performing preventive service on a high-mileage CTS-V, this DAYCO part ensures your supercharger runs at full efficiency. Proper belt tension is non-negotiable in supercharged applications—a slipping or worn belt will immediately compromise boost levels and throttle response. This OEM-equivalent belt is the correct choice for Cadillac CTS-V owners seeking reliable, verified replacement parts.
