High Torque Driveline Upgrades for Union’s Automotive Enthusiasts
Precision Engineering Meets Small Town Service for Unrivaled Reliability
Welcome to PEM Racing’s Union, Missouri location—your trusted source for performance grade driveline components tailored to the unique demands of central Missouri’s terrain. Situated just off Highway 47 near the historic Franklin County Fairgrounds and
a short drive from the rolling hills of Booneslick Trail Conservation Area, our Union branch serves drivers and builders from Washington to Fenton, St. Clair to Pacific, and everywhere in between. Whether you’re fine tuning
a drag car for the strip at World Wide Technology Raceway, reinforcing a trail rig for rugged runs on local gravel roads, or restoring a vintage muscle car that cruises through downtown Union’s brick streets, PEM Racing delivers
aerospace grade drive shafts, cryogenically treated axles, and reinforced rear housings engineered to perform—and built to last.
Leveraging advanced CNC machining, REM® surface enhancement, and liquid nitrogen cryogenic treatments, our driveline components eliminate vibration, maximize torque transfer, and resist fatigue under Missouri’s hot summers and frosty winters alike. With
same day technical consultations and next business day delivery across Franklin County, PEM Racing Union combines global engineering standards with genuine hometown hospitality.
