About National Differential

At National Differential, our mission has always been simple—provide customers with dependable differential and transfer case solutions they can trust. Founded with a passion for precision and a commitment to quality, we’ve grown into one of the nation’s 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 3-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.

We’ve established a reputation for honesty, integrity, and quality work. Don't just take our word for it, here's what our customers have to say:

  • "I just wanted to convey my sincere thank you for assistance in determining the best option for replacing my 2014 GMC YUKON DENALI FRONT DIFFERENTIAL. Just before I decided to purchase your part your management said I should give GMC Customer Service a call since I was barely out of warranty when it went bad. Your genuine interest in my situation saved me close to $3000.00 in total replacement cost when GMC Customer Service gave me a surprise call that they would cover it! National Differential did not lose a customer but gained something more and that is a Gold Referral Customer in me that will always refer people to National D when they need a replacement part.

Sincere regards,

Michael Werbowetzki, CEO, Continuum Group Inc."

  • "Geez! This is the best shop that I have been in or worked with! Here’s what happened. The transfer case totally locked up and broke in my Chevrolet 2500HD diesel pick-up truck. I couldn’t move an inch. I had a flatbed truck bring it to my home. I found National Differentials with a Google search and to my surprise they were in my hometown of Colorado Springs. Their beautiful website looked too good to be true with the colorful photos and spotless surroundings. I decided to drive to their address and verify if this shop was as good as their reputation. And to see if it was clean. Geez again! It was better that what I saw on their site. The interior of the shop was filled with beautifully painted rebuilt differentials and transfer cases lined up on spotless shelves and racks. When I arrived, I met Walt and he offered to give me a tour and explained how they could repair my truck and get me going in one day. He showed me the newly rebuilt transfer case that would go in the truck. I was so impressed with his knowledge from twenty plus years. One of the owners, George, came out to introduce himself as well. This simply doesn’t happen these days. Their manners were incredible. I had the same flatbed towing company deliver the truck to the National Differentials shop and Walt did the work to perfection with cleanliness and great expertise. I was given a warranty for three years and the truck runs perfectly again. All at a great price. I am so grateful for this group of experts who treated me so well. I recommend them without hesitation. There are many other good shops, but these guys are the best! Call them. They ship rebuilt parts across the globe and can give customers the correct advice."

  • "Hey everyone, if you are in the market for a differential, transfer case or looking to make those mods that you’ve been dreaming about doing. Give National Differential in Colorado Springs a call and talk to Walter. They have the parts and the experience to get the job done right the first time."

  • "Best rebuilder in the springs! Pricing is fair, staff is extremely knowledgeable. There isn't much they won't repair. They even keep rebuild units on the shelf for quick exchanges."

  • "This place is top notch! Super helpful, knowledgeable and friendly! Much to my chagrin they even delivered to Denver for a nominal fee. The warranty was excellent! I will be back!!"
