About Us

---

At Triple J Specialties, Motorsports come first. With over 20 CNC machines in-house, we manufacture the precision parts racers depend on to stay competitive.

Through our SpeedPartz and SpeedSprockets brands, we deliver CNC-machined sprockets and components for Sprint Cars, Lightning Sprints, and Micro-Sprints. Every part is crafted from premium USA materials and built start-to-finish in our facility for unmatched strength, consistency, and value.

Unlike other shops, we handle all finishing in-house — including anodizing and powder coating — with no outsourcing. From raw material to finished product, 100% of the process is done under our roof, ensuring complete control over quality, turnaround, and performance.

Our machining expertise and racer-focused mindset ensure your parts are built to win. Trusted nationwide, we stand behind every part,and every finish—because we’re racers too.

 Racing isn’t just what we do—it’s who we are. The Mackison family has deep roots in the sport, and we’re proud to say we are racers and drivers ourselves. From long nights in the shop to laps on the track, our firsthand experience gives us the insight to design and build parts that truly perform.
