The Power Behind the Haul: Custom Springs & Wire Forms for the Trailer and Towing Industry

Discover how Ace Wire Spring & Form Co., Inc. supports the trailer and towing industry with custom springs and wire forms engineered for lift gates, docking systems, and more. Trusted by leading trailer brands and proudly made in the USA.

Custom Springs That Keep the Trailer Industry Moving

When it comes to the trailer and towing industry, performance and reliability are everything. Whether you’re hauling heavy loads across the country or supporting critical last-mile deliveries, the components behind the scenes matter. At Ace Wire Spring & Form Co., Inc., we specialize in manufacturing custom springs and wire forms that power the trailers, lift gates, and docking systems trusted across America. With over 85 years of experience and full membership in the National Association of Trailer Manufacturers (NATM), we’re proud to support this essential industry.

Off-the-shelf solutions simply don’t cut it for many trailer applications. The rugged environments, variable loads, and constant vibration demand springs and wire forms engineered for performance, durability, and precision. That’s why Ace Wire Spring has invested in a dedicated engineering department that works directly with trailer manufacturers and their design teams to provide expert design assistance. Whether you’re refining a prototype or developing a new suspension system, our engineers help identify the right materials, tolerances, and spring configurations to meet your goals.

Applications We Support

Ace Wire Spring provides a wide range of spring and wire form solutions that support critical trailer applications. Our capabilities span across diverse industries, and we understand the unique needs of heavy equipment, agriculture, logistics, and beyond. Some of the key trailer-related applications include:

• Trailer Suspension Systems – Heavy-duty compression springs that absorb shocks and improve ride quality for flatbeds, utility trailers, and enclosed haulers.
• Lift Gate Assist Springs – Torsion or extension springs that counterbalance the weight of hydraulic lift gates, making them safer and easier to operate.
• Docking Mechanisms – Wire forms and spring systems that secure doors, ramps, and cargo during loading and unloading.
• Hinges and Latches – Precision torsion springs that maintain tension in latching mechanisms or doors on utility trailers.

Built for the Road — and the Long Haul

Springs in the towing industry face harsh conditions — temperature fluctuations, road salt, dirt, and continual stress from towing and braking forces. Ace Wire Spring engineers select materials and finishes that stand up to real-world environments. We manufacture using carbon steel, stainless steel, and specialty alloys as needed, and we provide optional coatings and heat treatments to extend spring life.
