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.
