American Racing Solutions LSA Billet Racing Belt Tensioner 60 lb. Spring (86560) - 2009-2015 CTS & 2012-2015 Camaro ZL1
Upgrade belt control on your high-performance GM application with the American Racing Solutions LSA Billet Racing Belt Tensioner. Precision CNC-machined from 6061-T6 billet aluminum, the ARS 86560 is engineered to provide increased strength, reliable belt tension, and improved performance under demanding high-RPM and supercharged conditions.
At the heart of this tensioner is a custom-wound 60 lb. spring that is approximately 20% stronger than the factory spring. The increased spring force helps maintain belt engagement under heavy load, reducing unwanted belt slip and supporting more consistent supercharger performance. A hardened steel shaft and heavy-duty bearings provide additional durability for high-horsepower street and racing applications.
Unlike cast factory-style components, the ARS tensioner is machined from solid billet aluminum for excellent rigidity and precision. It is designed as a direct bolt-on replacement, eliminating the need for adapter plates or additional mounting accessories on compatible applications. An anodized finish provides corrosion resistance while helping reduce belt wear.

60 lb. High-Tension Racing Spring
High-horsepower supercharged engines can place substantial loads on the accessory and supercharger belt drive. The ARS 86560 uses a custom-wound 60 lb. spring to provide approximately 20% more spring force than the factory tensioner. This additional tension helps maintain belt grip during rapid acceleration and elevated engine speeds, reducing slip that can lead to inconsistent boost and performance.
Billet Aluminum Construction
American Racing Solutions machines the tensioner from solid 6061-T6 billet aluminum rather than relying on a cast housing. This construction provides the strength, precision, and rigidity needed for demanding performance applications while maintaining a lightweight design. A hardened steel shaft and heavy-duty bearings further reinforce the assembly for reliable operation.
Pulley Options
- No Pulley
- 80mm 8-Rib Double Bearing Grooved Pulley
- 80mm 10-Rib Double Bearing Grooved Pulley
- 80mm 12-Rib Double Bearing Grooved Pulley
Ceramic bearing upgrades are available for each pulley configuration, allowing you to select the setup that best matches your belt drive system and performance requirements.
