American Racing Solutions Billet Belt Tensioner - Street (9740C) - 2000-2004 Cobra
Improve belt control and reliability on your supercharged Mustang Cobra with the American Racing Solutions Street Billet Belt Tensioner. Designed specifically for street-driven and daily-driven 2000-2004 Ford Mustang Cobra applications, this upgraded tensioner features a 40 lb. spring that provides improved belt tension while maintaining a street-focused configuration.
Precision CNC-machined from solid 6061-T6 billet aluminum rather than cast material, the American Racing Solutions Cobra tensioner delivers the strength, accuracy, and durability required for upgraded supercharged combinations. A custom-wound street spring, hardened steel shaft, and heavy-duty bearings work together to provide dependable belt control under demanding driving conditions.
The 40 lb. Street version uses a lighter spring than the American Racing Solutions Race model, making it better suited for Cobras that see regular street and daily driving. Even with its street-oriented design, it provides significantly improved belt tension and reliability compared to the factory tensioner, helping combat belt slip as power and supercharger demands increase.
