About HSP Diesel - American Made Diesel Performance Parts & Upgrades

HSP Diesel began in 2010 when founder, Joe, started fabricating custom parts for his own Duramax in the corner of his dad’s barn. What began with a single workbench, a welder, and a handful of friends asking for parts quickly grew into something much bigger than expected.

From those humble beginnings, HSP has grown into a full-scale manufacturing company with nearly 40 employees, supporting dozens of families and fueling a community of diesel enthusiasts nationwide.

At their core, they are fabricators, engineers, and diesel enthusiasts. Every product that leaves HSP is designed, engineered, machined, welded, laser-cut, bent, powder coated, assembled, and shipped under one roof. By keeping everything in-house - from flat laser and mandrel tube bending to powder coating and shipping - they ensure unmatched quality, innovation, and speed.

HSP Diesel builds performance parts for Duramax, Powerstroke, and Cummins platforms, each designed to push limits while delivering the reliability our customers demand.

Today, HSP Diesel is recognized as a leader in the diesel aftermarket industry, but we haven’t forgotten where we came from. They are grateful for the loyal retailer and customers who made this journey possible and committed to driving innovation that supports both our community and the families who make HSP what it is today.

At HSP, they are driven to create the highest-quality products, deliver exceptional service, and invest in the growth of their team. Aiming to leave a lasting, positive impact on both our employees and our customers - making every interaction not just a transaction, but a meaningful and enjoyable experience.
