D&J’s Drew Pumphrey and the FSR Piston

We’ve been collaborating with D&J Precision Machine for a little while now to help create more diesel content for you all to enjoy. Shop owner Drew Pumphrey and the whole team at D&J are always upping the game when it comes to diesel engine work and component production. Whether it’s building the fastest diesel engine on the planet for Firepunk Diesel, or its creating new products for Cummins applications, or helping customers build diesel engines for everything from mild to wild, there are plenty of reasons why D&J was our 2020 America’s Best Engine Shop for the Diesel category.

We recently caught up with Drew at the 2021 Ultimate Callout Challenge to chat about one of the shop’s most successful products – the FSR piston with a steel ring land. Its a perfect upgrade for many high-horsepower applications.
