Precision Engineering & Durability for Suburban and Track Enthusiasts

Located just north of the Hollywood Casino Amphitheatre and moments from Creve Coeur Lake Memorial Park, PEM Racing extends its race-proven driveline expertise to Maryland Heights. We manufacture custom CNC-machined drive shafts, REM-microfinished ring & pinion gear sets, quick-change rear ends, and complete 9″ Ford rear end kits—each engineered for the rigors of drag strips, dirt ovals, and spirited street cruising. Our components are cryogenically treated and microfinished at our Saint Clair, MO facility, delivering the resilience and reliability you demand whether you’re carving through the loop roads of Westport Plaza or lining up at nearby World Wide Technology Raceway.

Samantha Prather

The customer service is amazing, Brock and Taylor did a wonderful job helping out and making sure all my questions were answered! Also from ordering to picking up my driveshaft was also super quick and awesome! Can’t say enough great things about PEM! Thank you so much :)

Ryan Higginson

Ordered a rearend housing and axles on eBay from pem. Talked to Brock before placing the order to ensure you it was the one I needed for my project. I was informed it would take 5-7 days to build and time to ship to me. Needless to say I ended up getting it to my door in 5 days. Like 5 days not 5 business days. Beyond happy about that and they sent me an amazing product
