Our custom axle building process starts with a detailed consultation to determine your vehicle’s needs.
When performance, dependability, and precision matter most, having the appropriate components in place makes all the difference. However, off-the-shelf parts do not always match the needs of certain vehicle owners, which is where personalized solutions come in, ensuring you get exactly what you are looking for, with no compromises.

At Interstate Repair Service, we understand that no two owners are alike, nor are their vehicles. If you come to us for custom axle building services, we will fabricate an axle that is tailored to your vehicle or equipment’s specific needs. Whether you’re upgrading for heavy-duty hauling, off-road performance, racing, or industrial use, a custom-built axle provides maximum strength and reliability where standard options fall short.
The custom axle building process starts with a detailed consultation to determine your individual needs. We examine load capacity, topography, horsepower, torque needs, and intended application. From there, we create an axle assembly that is specific to your application, choosing the best materials, shaft specifications, spline configurations, and differential compatibility to offer peak performance.
Precision is at the core of everything we do. Each axle is designed with high-quality components and produced to tight tolerances to ensure accurate alignment, smooth operation, and a long service life. We also provide enhanced bearings, strengthened housing, unique widths, and customized finishes to improve operation and durability.
Our locally owned and operated team has provided drivers in the Knoxville, Tennessee area and beyond with quality service since 1980, and we would be honored to help you as well. Additionally, we offer a nationwide warranty to further increase your peace of mind.
