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.
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
