Battle Motors

We are excited to announce AFS is your new local Battle Motors Dealership!

Battle Motors (formally Crane Carrier Company) has evolved as a leading manufacturer of specialized heavy-duty mobile equipment. For over 50 years, Battle has maintained a distinctive reputation as a leading producer of custom-built heavy-duty carriers, designed for specific job-site applications with efficient operation under extreme on-and-off road conditions.

Each of Battle Motor’s chassis products are engineered to fulfill special or “extreme” operational service requirements which are not otherwise met by mass producers of Class 8 trucks.

Battle Motors has the people with experience, engineering ability and dedication to develop new chassis products and provide the necessary support to make the difference. Battle Motors and AFS remains small enough to serve our niche markets well, and big enough to make a significant difference. Battle Motors chassis are designed to interface with our customer’s needs, products and specific market vocations. Now AFS can help you design and build the truck that meets your specific needs to get the job done. Click here for more information.

Engine Components

Competing in today’s marketplace demands maximum equipment uptime. Unscheduled breakdowns must be resolved immediately to meet deadlines and control costs. AFS responds to these needs with rapid action offering new, exchange or in house remanufacturing options.

With over 40 years of remanufacturing experience, we have developed clearly defined standards for every step of the remanufacturing process. Each unit is carefully identified, completely disassembled and cleaned. Component parts are qualified and tested with wear parts being reconditioned or replaced. Units are then reassembled and the assembly is subjected to further testing and inspection before being packaged and inventoried.

If you have been replacing any of your components with new assemblies, consider AFS’s component repair and remanufacturing services. Our work is fully warrantied. We can restore your components to like new condition for far less than new replacement costs. Click here for more information

Transmission Remanufacturing

AFS is proud to announce that transmission remanufacturing has been added to our long list of service options! Specializing in Allison Transmissions, our AFS experts will give new life to your old transmission. All remans start with our commitment to you, the customer, the commitment to using genuine parts & original factory building specifications.

We build all of our transmissions from the ground up. Meaning we begin by carefully identifying each transmission. Then they are disassembled and cleaned. Next, each part is carefully inspected and qualified to determine if and what new components may be needed or reconditioned. Transmissions are then reassembled and subjected to rigorous testing before being prepared for install or shipment.


Creating custom fabricated bumpers for units when the factory style just doesn’t meet our Customer’s needs, is just one of the many benefits to choosing AFS for all your custom fabrication needs. Our small but talented Production Team are a hands on group that take pride in machining, welding, assembling, and installing everything from our Stellar Industry Hook lifts to Buyers SnowDogg snow plows. Using our state of the art Torchmate CNC Plasma Table allows AFS to give our Customer’s endless possibilities for all their fabrication needs

A hook lift truck is the ultimate in productivity and versatility, and Stellar’s NXT Series, Shuttles and Sliders lead the way. With just one hook lift truck and one operator, you can handle a wide range of jobs per day. Just change the body and move on to your next task, quickly and easily. AFS’s Production department is the place for all your hook lift needs.
