UPR Products

UPR Products was born on the drag strip. Drag racing legend Mark Mainiero and his Joe founded UPR in 1989 to sell Mustang suspension components that they had designed based on their experience on the strip. UPR's suspension packages have found their way onto some of the most powerful drag-strip Mustang on the road because. All of UPR's suspension components were purposely designed to be lightweight, easy to install, high-performing, and easy to adjust and fine tune to meet the needs of nearly any Mustang performance application. While it's easy to get a ton of power out of Mustang performance parts, it's a bit tougher to get the traction needed to get it all down which is why some of UPR's best designs are their Mustang chromemoly control arms that save on weight while stiffening up your Mustang's rear end to transfer more power to the pavement. UPR has recently expanded into throwing together some Mustang billet interior parts, including some impressive Mustang interior packages.
