BilletFlow Cobra Idler Pulley Kit
Swapping out to a smaller supercharger pulley is the easiest way to add power to your 2003-2004 Cobra short of a tune. However, the smaller you go, the less contact area the belt has on the pulley. This leads to the belt slipping.
Luckily BilletFlow devised the solution by way of this Snub Idler & Pulley Kit. If the belt is slipping, then you are not achieving full boost. This snub idler and pulley kit will not add power itself, but the elimination of belt slip allows full boost which is where the power increase comes from. It utilizes three 100mm Idler Pulleys, one 92mm pulley and is a simple bolt on installation. It is black anodized for long lasting good looks. Plus, the new billet idler pulley allow for reliable operation, unlike the stockers.
Bought the kit form LMR as they had the best price and it was available. Great looks and comes with all hardware to install. Had a small problem and LMR rectified it ASAP and got me what I needed. Top notch part and customer service
