American Racing Solutions COPO 2.6L Magnuson Belt Tensioner (ARS86218DB) - GM COPO and Magnuson 2.6L Applications
Take control of belt stability and maximize power delivery with the American Racing Solutions COPO Belt Tensioner, engineered specifically for 2.6L Magnuson supercharger applications. Designed for high-horsepower race environments, this upgraded tensioner eliminates the weaknesses of factory components and delivers unmatched strength, durability, and performance.
Unlike factory cast units, this tensioner is precision machined from 6061-T6 billet aluminum for superior strength under extreme load. Internally, it features a TGP shaft, hardened bushings, proprietary spring system, and thrust bearings to ensure smooth operation and long-term reliability. Proven on both the dyno and track, this system helps reduce or eliminate belt slip, resulting in more consistent boost and increased horsepower.
Performance and Reliability
This tensioner is designed to withstand the added stress of high boost and aggressive racing conditions. By maintaining proper belt tension, it improves supercharger efficiency and ensures consistent performance across every pass.
Direct Bolt-On Upgrade
Engineered as a direct replacement for the factory unit, this tensioner installs without the need for additional brackets, adapters, or modifications. It delivers a straightforward upgrade with race-proven results.
Included Pulley
This kit includes a 76mm 10 rib black anodized billet aluminum idler pulley featuring a double bearing design for increased strength and stability under load.
