About Us
// About Over-Under Racing
Founded by racers, for racers.
At Over-Under Racing, we're passionate about go-kart racing, and even more passionate about the racers who fuel the sport at the grassroots level. Our mission is to support the karting community with quality parts and personalized service with fair, competitive pricing on everything we sell, so you can focus on performance, not your wallet.
Whether you're gearing up for a club race, a regional race, or a national event, you'll find everything you need in our retail store in Lewisville, TX or on our modern online shop, open 24/7 and stocked with trusted brands and essential components.
Race-Day Ready
Zero downtime, on and off the track.
Do you race locally in the Dallas, Fort Worth, TX area and need your parts fast? We've got you covered. In addition to nationwide shipping, we offer convenient pickup options in our retail store or a trackside pickup option at select races as well. For trackside pickup, check our event schedule, order online, and choose pickup at the race we're attending at checkout. We also stock a selection of common parts at the track, so if something breaks on race day, there's a good chance we've got you covered.
From first-time karters to seasoned pros, we're more than just a parts supplier — we're your racing partner, dedicated to helping you chase the checkered flag.
