Tensioner Idler Assembly 03 SVT Cobra

This extra idler pulley creates more belt wrap and holds the belt tighter against the supercharger pulley, for less belt slip and more boost. Vitally important for maximum supercharger output, it is especially effective at higher boost levels when the engine is equipped with a smaller supercharger pulley. Comes with a hardcoat-anodized billet-aluminum pulley, high quality bearings, an anodized billet mounting bracket and all hardware to mount to the engine.
