Build more power, improve reliability, and get the most out of your diesel setup with the Diesel Performance range from Prime Speedworks.

Whether you're upgrading a hard-working tow rig, building a high-output street vehicle, or putting together a serious competition diesel, the right components make all the difference. Our diesel performance collection brings together quality parts designed to support increased boost, fuel delivery, airflow, engine strength, monitoring, and overall performance.

From supporting modifications through to components for serious horsepower builds, we focus on products suited to real-world performance applications where strength, consistency, and reliability matter.

OUR STORY

Prime Speedworks was built at the track, not in a boardroom.

With decades of real motorsport experience, we’ve gone fast across it all — V8 Supercars, Offshore Powerboats, Sprintcars, Midgets, and Drag Racing from Top Fuel to Super Sedan, including the brutal world of Drag-and-Drive.

We don’t chase hype — we back proven performance. Every product we support is chosen because it survives real racing, not because it looks good on a shelf.

If it doesn’t make you faster, stronger, or more reliable, it doesn’t belong at Prime Speedworks.
