Axletrac Alignment Tools, Inc.
Direct Distributor for Heavy-Duty Trailer Axle Alignment Tools in the U.S., Canada, and Worldwide
Axletrac revolutionizes semi trailer axle alignment by eliminating inefficiencies found in traditional methods. Industry experts agree that extending axle end measurement points beyond the outer edges of tires significantly improves accuracy. Our patented axle extenders simplify this process by attaching directly to hub-piloted wheel studs—eliminating the need to remove hubcaps, tire inflation systems, or hubodometers. Unlike fragile rim-based tools, Axletrac uses durable wheel studs as reference points, creating a solid, self-centering structure that ensures consistent and repeatable precision.
Get trailer manufacturer-recommended alignments with our heavy-duty axle extenders and exclusive Kingpin Extender Pogo Stick, ensuring precise axle positioning for improved tire wear, fuel efficiency, and overall performance. Axletrac alignment components are precision-manufactured in the United States. Some accessory items included in our kits—such as tape measures or spring scales—may be globally sourced.
Heavy-Duty Durability
Axletrac tools are built to withstand the toughest shop environments with rugged, high-strength materials. The design includes thick steel tubing and solid steel pins to prevent bending or wear. There are no delicate components, eliminating the risk of breakage. The tools require no recalibration or fragile sensors and are built for long-term, repeatable use. Designed by a former shop manager, Axletrac alignment tools are made for real-world conditions. This is the last alignment tool you’ll ever need to buy.
Proven Accuracy
Self-centering technology ensures true-to-hub measurements for precise alignment. The tools have been tested across hundreds of wheel-stud positions and achieve less than 1mm of variance, outperforming traditional methods. Axletrac eliminates guesswork and rim-edge errors, ensuring correct axle parallelism. No lasers or stringing are required, providing fast and accurate results in minutes. Preventing one misdiagnosed alignment issue offsets the cost of the tool.
Industry Standards & Innovation
Axletrac tools align with SAE J875 standards, ensuring compliance with manufacturer guidelines. No strings, lasers, or tire removal are needed, simplifying the alignment process. Manufacturers recommend checking alignment every 5,000 miles. Axletrac simplifies the process, making it a fast and efficient job for a single technician. The system is compatible with pneumatic tankers, low boys, flatbeds, reefers, livestock trailers, and more. Axletrac tools work with 8-stud and 10-stud hubs, with Budd adapters available for older models.
