Founded in 1989 by Joe and Mark Mainiero, UPR Products began as a small South Florida performance shop known as Super Stang, where racing innovation was the family business. From the early days of record-breaking street Mustangs to the company’s evolution into a full-scale manufacturing powerhouse, UPR has remained focused on one mission: building high-quality, American-made performance parts that help racers win.
Today, UPR Products operates out of a 20,000-square-foot facility in Lake Worth, Florida, where it designs, manufactures, and tests a comprehensive line of suspension components, oil catch cans, billet accessories, and performance products used by championship-winning racers across the NMRA, NMCA, and other major series. With decades of real-world racing experience and a commitment to customer service and trackside support, UPR continues to push the limits of what’s possible for drag racers and performance enthusiasts.
