<h3>About Andersen Manufacturing (Andersen Hitches)</h3><p>Andersen Manufacturing — better known under the <strong>Andersen Hitches</strong> trade name — has been a cornerstone of the American towing industry for over six decades. A family-owned, US-based company headquartered in Idaho Falls, Idaho, Andersen has been selling quality, American-made products for over 50 years. What began as a single-room workshop has evolved dramatically: the company has grown into a 102,000 square foot manufacturing and fabrication complex, further expanding by 70,000 sq. ft. in 2021 to meet growing demand and better serve dealers across the country.</p><h3>A Legacy of Innovation in Towing</h3><p>Since its beginnings, Andersen has introduced many &quot;firsts&quot; to the trailer hitch and towing industry — from the lightweight design of the Ultimate 5th Wheel Connection to the simplicity of the Rapid Jack tire-changing accessory. The engineering philosophy behind these products is rooted in material science as much as mechanical ingenuity: Andersen uses aircraft-grade aluminum — one of the toughest metals available — to build hitches capable of handling 40,000 pounds, with tested strength up to 55,000 lbs, while remaining corrosion-resistant for year-round use.</p><p>Andersen trailer hitches and towing accessories are tested to comply with all V5 and SAE J684 standards, and the company has introduced groundbreaking products including the first-ever Alumistinger ball mount made from aluminum and the Rapid Hitch adjustable ball mount. Nearly every Andersen Hitches product comes with a lifetime warranty — a testament to the confidence the brand places in its own craftsmanship.</p><h3>More Than Just Hitches</h3><p>Andersen Hitches serves the towing industry with a complete line of popular trailer hitches and unique towing products for both trailers and 5th wheels. That ecosystem extends well beyond the hitch receiver itself. Properly lighting your trailer is critical for road safety and legal compliance, which is why Andersen also offers <a href="/1303-anderson-manufacturing-clearance-marker-lights-incandescent-200266">clearance and marker lights</a> and <a href="/1303-anderson-manufacturing-side-marker-light-2824">side marker lights</a> designed to keep your rig visible in any condition.
