Protofab Racing

Protofab Engineering has been making quality parts for every necessity since the 1980’s. For twenty plus years a team of passionate engineers and machinists have dedicated their time to providing quality parts to both our clients and our very own Protofab Racing.

For over 10 years Protofab Racing has been the pride of Protofab Engineering with our company’s very own founders Duane and John Nelson paving the way to success as our racing team and shops founders. While John Nelson no longer suits up for the track himself, we still run a 360-Winged Spring Car on dirt tracks that range from a quarter to a half a mile long. Our racing legacy is succeeded by the Aussie Outlaw Brooke Tatnell, who began his racing career in Australia in 1987. As a 7-time World Series Sprintcars champion, we could ask for no one better to represent us on the track!

We’d be thrilled to see you come out to the races. Whether in the shop or on the track, Protofab Engineer’s team’s passion shines.
