Local Repair & Replacement

At National Differential we can repair or replace your differential or transfer case locally helping save on time and money.

At National Differential, we provide professional differential and transfer case repair services for many passenger cars as well as most light-duty and medium-duty trucks. Unlike many repair facilities that only offer complete unit replacement, our experienced technicians can often repair or rebuild your existing differential or transfer case, helping you save both time and money. With over 30 years of drivetrain experience, we are committed to delivering unmatched customer service through honest communication, accurate diagnostics, and quality workmanship. Whether your vehicle needs a simple seal replacement, bearing service, or a complete rebuild, our team is dedicated to getting you back on the road as quickly as possible. For added peace of mind, most repairs completed with parts supplied by National Differential are backed by our standard 2-Year / 24,000-Mile Warranty, whichever comes first.

In addition to repairs and rebuilds, National Differential specializes in gear ratio changes and performance drivetrain upgrades for off-roading, towing, racing, and drifting applications. Installing larger tires on your truck, Jeep, or SUV can significantly impact performance, fuel economy, and transmission operation. A properly selected gear ratio can restore lost power, improve throttle response, and help your vehicle perform the way it was intended. For customers who tow heavy trailers, boats, campers, or work equipment, a gear swap can improve pulling power, reduce strain on the transmission, and provide better overall drivability. We also offer performance gearing solutions for racing and drifting enthusiasts looking to maximize acceleration and optimize vehicle setup for their specific driving style. Whether you're building an off-road rig, upgrading a tow vehicle, or enhancing a performance vehicle, our experienced technicians can help you select the right gear ratio and differential components to meet your goals.
