Metco Motorsports 2009+ Cadillac CTS-V Supercharger Idler Pulley
METCO MOTORSPORTS
In CTS-V applications using a smaller than stock supercharger pulley, belt slippage at higher engine speeds can reduce both boost and power. The larger diameter of this pulley serves to increase belt wrap at the supercharger pulley, as well as increase tension on the supercharger belt. This pulley is an easy bolt-on solution to troublesome belt slippage.
Note: Image shows installation using the factory hex head bolt. As shown in the other images, a billet bearing cover and a stainless steel socket-head fastener are included to secure the pulley for a more finished appearance.
