ST. CLAIR, Mo. (April 24)—Performance Engineering & Manufacturing is sponsoring the return of the USRA Iron Man Stock Car Series with a two-step approach in 2025.

Each night, the fourth-place finisher in the USRA Stock Car feature race will receive a PEM product certificate for a free PEM 610 series PEM Quick Change Gear Set.

The big news is this: At the 2025 awards banquet there will be a drawing for a new Terminator Chassis, and it will include a PEM Standard Quick Change rear end with hubs, rotors and axles.

"I'm just excited to help this Stock Car Series in 2025," said PEM Sales Manager Randy Harrison. "These racers are the heart of racing and many times have the closest racing every night."

PEM Racing manufactures nine-inch Ford rear ends and gears, quick change rear ends, quick change gear sets and driveshafts. The nine-inch Ford gear center sections are built with all new parts for durability.

Quick change rear ends are available in standard and the Black MAX option rears with REM ISF polished and lightened internals. The most popular quick change gear sets sold are the 650 series polished LW set.

Another service PEM Racing offers is REM ISF polishing of customer supplied parts for reduction of friction—usually gears, wheel bearings, transmission and internal engine parts.

PEM Racing is proud to be located in the Midwest and is celebrating it’s 18th year in business. The location in St. Clair, Mo., is just 45 miles west of St. Louis on I-44.

You can find PEM Racing products at www.pemracing.com, email sales@pemracing.com or call (636) 629-6200. PEM Racing also supplies many local parts dealers, warehouses and chassis builders.
