Description

The COMP Cams Belt Tensioner with Idler (Part #54021) is engineered to improve the reliability of your GM LS engine’s serpentine belt system.

Designed specifically for GM LS1, LS2, LS3, LS6, LS7, and LS9 engines, it is an essential upgrade for high-performance and daily-driven applications alike. For 2010 and newer Camaros, the belt must be replaced when installing this tensioner to ensure proper fitment and operation.

The installation process is straightforward, making it suitable for both professional mechanics and experienced DIY enthusiasts. This component is compatible with a range of vehicles, including Chevrolet Camaros from 2007 to 2015, Chevrolet Corvette models from 2000 to 2013, Pontiac G8 from 2009, and other GM vehicles that utilize the LS series engine. Proper tensioning of the serpentine belt is crucial for efficient operation of accessories such as the alternator, power steering pump, and AC compressor, and the COMP Cams tensioner ensures these components operate smoothly under demanding conditions. This part is not CARB-approved but complies with all relevant standards and is designed to meet or exceed OEM specifications for performance and durability.
