Fleet Diesel Repair in Yuba City, CA

NorCal Diesel Co. is a diesel performance and parts company built by people who live and breathe diesel trucks. What started as a hands-on diesel repair operation has grown into a trusted source for high-quality diesel parts, performance upgrades, and reliability solutions for Powerstroke, Duramax, and Cummins platforms.

We specialize in products that solve real-world problems — from airflow and fuel delivery to drivability, towing performance, and long-term reliability.

Every product we carry is selected with one goal in mind: help diesel truck owners get dependable performance out of their trucks. Whether you’re daily driving, towing heavy, or upgrading for efficiency and power, we focus on parts that are proven, compatible, and built to last.

Our catalog includes:

Cold air intakes

Performance-focused diesel parts

We don’t chase trends — we stock parts that we would run on our own trucks.

Experience You Can Trust

Our background in diesel service and diagnostics gives us a deeper understanding of how parts perform once they’re installed. That experience helps us guide customers toward the right part the first time, reducing guesswork and unnecessary returns.

If a part doesn’t make sense for a specific application, we’ll tell you.

While NorCal Diesel Co. is rooted in Northern California, our online store serves diesel truck owners across the country. We work with trusted manufacturers and suppliers to ensure fast shipping, accurate fitment information, and consistent product quality.

No matter where you’re located, our goal is the same:

Our Mission

To provide diesel truck owners with reliable parts, honest guidance, and performance solutions that help their trucks work harder, last longer, and perform better — without unnecessary upsells or confusion.
