  • PDI diesel treats you like family. They take the time explaining things to you. I had no idea they could make my semi-truck diesel run that strong. If performance is on your mind—as far as I'm concerned—there's nothing like PDI diesel.

  • Always the best service and fast! I'm very particular about my trucks, PDI is always clean and careful with my trucks.

  • This is the only place to take your truck for all your performance needs!

  • "I save 45 minutes in drive time and... $300 per month in fuel savings. It's nice to not work the truck so hard so I have a lot more longevity in the life of the motor.

We understand that your truck isn’t just your equipment it’s your lifestyle. Our longtime involvement in the trucking industry has helped us recognize the challenges of OEM equipment such as inefficiency, low quality parts, and being underpowered.

Rather than simply replacing low quality parts with other low quality parts we set out to make it our mission to change what is expected of a heavy-duty diesel engine. Before PDI begins development on any new product we ask how will this increase reliability, increase horsepower, increase torque and improve fuel efficiency.

Since being founded in 2001 we have grown to become the leader in the market with a reputation for products with unmatched quality and performance.

You work hard, enjoy the drive!
