Reduce power robbing belt slippage and improve belt tension when upgrading the supercharger pulley on your 2003-2004 Mustang Cobra with this premium, 100mm idler pulley kit from UPR. This kit will feature quality machined billet aluminum construction and offers an industry-leading double-roller sealed bearing design for added strength, reliability, and durability. UPR produces this USA-made kit with a black hard-coat anodized finish which provides corrosion resistance and ultimately prolongs the longevity of the pulley. This pulley kit will be the perfect upgrade for anyone with an upgraded tensioner assembly with increased belt wrapping and can be installed on your engine in less than 10 minutes in most cases!

Product Note

When an existing 90mm pulley is replaced with a larger 100mm pulley, 0.5” must be added to the required belt length. Reference our belt guide for proper belt length.

About This Brand

In 1989, Mark Mainiero and his son Joe started UPR Products with Mustangs in mind. With the help of their employees Jeremy Martorella and Bart Tobener, they brought in more racing victories and records than any other shop of that time. In 1998, Joe recognized the need for a company that fully understood the Mustang racer's suspension needs. While making customer service his main priority, he strived to offer the strongest, lightest, and highest quality parts at an affordable price. A firm believer in the “keep it simple” philosophy Joe made sure all his components could be easily installed and adjusted. Shop UPR for high quality Mustang performance and dress up components.
