Anderson Manufacturing

<h3>About Andersen Manufacturing</h3><p>Andersen Manufacturing — better known to the towing community as <strong>Andersen Hitches</strong> — has spent over six decades engineering some of the most trusted trailer hitch and towing products made in America. <a href="/1303-anderson-manufacturing">Founded in 1958</a> and headquartered in Idaho Falls, Idaho, this family-owned company grew from a single-room shop into a 102,000-square-foot manufacturing and fabrication complex, all while keeping production firmly on U.S. soil.</p><h3>American-Made Innovation in Every Product</h3><p>What sets Andersen apart from the competition is a relentless commitment to rethinking the way towing gear is designed. The company pioneered the first-ever aluminum Alumistinger ball mount and the popular Rapid Hitch adjustable ball mount — products that redefined what towers expected in terms of weight savings and versatility. Their Ultimate 5th Wheel Connection, crafted from aircraft-grade aluminum, delivers a rated tow capacity of 24,000 lbs while tipping the scales at just 35 pounds — a remarkable feat that makes installation, removal, and storage genuinely practical.</p><p>Their weight distribution hitch similarly breaks the mold. Rather than relying on heavy spring bars, Andersen&apos;s innovative tension chain system redistributes trailer tongue weight while simultaneously providing sway control — all in a package that weighs less than 60 pounds and operates with far less noise than traditional setups. It&apos;s the kind of engineering-first thinking that has earned Andersen a loyal following among RV enthusiasts, weekend adventurers, and serious haulers alike.</p><h3>Built to Last, Backed by Warranty</h3><p>Andersen Manufacturing stands behind its products with confidence: nearly every item in the lineup is covered by a <strong>lifetime warranty</strong>. Every hitch and towing accessory is tested to meet V5 and SAE J684 standards, so customers can tow with peace of mind knowing their gear has been put through rigorous quality verification. From <a href="/1303-anderson-manufacturing-flare-fitting-17445">precision-fit flare fittings</a> for trailer hydraulic brake lines to <a href="/1303-anderson-manufacturing-side-marker-light-2824">side marker lights</a> that keep your trailer visible and road-legal, Andersen&apos;s catalog covers the full spectrum of what a well-outfitted trailer demands.</p><h3>A Complete Trailer Accessory Ecosystem</h3><p>Beyond hitches, Andersen&apos;s product ecosystem extends to the smaller details that make a big difference on the road. Properly functioning <a href="/1303-anderson-manufacturing-clearance-marker-lights-incandescent-200266">incandescent clearance and marker lights</a> ensure your trailer profile is visible to other drivers day and night, while marker lighting solutions keep you compliant with federal lighting regulations. A reliable <a href="/1303-anderson-manufacturing-tail-light-assembly-15029">tail light assembly</a> rounds out the safety picture, providing crisp brake and turn signal illumination to the vehicles behind you. Together, these components reflect Andersen&apos;s philosophy that a safe tow isn&apos;t just about the hitch — it&apos;s about every connection point from truck to trailer.</p><h3>Why Towing Enthusiasts Trust Andersen</h3><ul><li><strong>Family-owned and American-made</strong> since 1958, built in Idaho Falls, Idaho</li><li><strong>Aircraft-grade aluminum construction</strong> for lightweight strength and corrosion resistance</li><li><strong>Lifetime warranty</strong> on nearly every product in the lineup</li><li><strong>SAE J684 and V5 tested</strong> for safe, standards-compliant performance</li><li><strong>Industry-first innovations</strong> including the Alumistinger and Rapid Hitch ball mounts</li><li><strong>Full trailer ecosystem</strong> covering hitches, lighting, fittings, and accessories</li></ul>
