National Differential
& Transfer Case

At National Differential, our mission has always been simple—provide customers with dependable differential and transfer case solutions they can trust. Founded in the 1980’s with a passion for precision and a commitment to quality, we’ve grown into one of the nation’s largest and most trusted suppliers for remanufactured differentials and transfer cases.

Our journey began by recognizing a need in the market: customers and shops alike want differentials and transfer cases that are not only reliable but also backed by strong warranties and exceptional service. From the start, we’ve focused on doing things right the first time. Every unit we build is carefully remanufactured to meet or exceed OEM specifications, ensuring long-lasting performance.

Over the years, we’ve built lasting relationships with customers across the country—from local shops to individual vehicle owners—who know they can count on us for honesty, expertise, and fast turnaround. Our highly trained technicians, combined with the dedicated and knowledgeable office staff, work together to make sure each customer gets the right product, at a fair price.

Today, National Differential is proud to back most units with a 2-year warranty and to continue raising the standard in the drivetrain industry. While technology and vehicles are evolving, one thing remains the same: our promise to treat every customer with integrity and to provide products built to keep you moving.
