Blackbird Performance Supercharger Belt Tensioner

Our supercharger belt tensioner was developed to replace the factory style tensioners that have neither the strength, range of motion, tension and damping that is optimum or required to make supercharger belt drive systems function with minimal power robbing belt slippage and/or prevent belt/system failures. The tension and internal damping are carefully matched to provide smooth and continuous control even in extreme events such as two step / rev limiters and sudden and repeated drop throttle. The heavy duty and all billet construction combined with these less obvious, highly engineered features make this tensioner far superior to others, and with the included billet pulley of your choice (10 or 12 rib) are offered at a very high value price while being Made in the USA.
