Blue Ox

<h3>Blue Ox: A Century of Towing Excellence</h3><p>Few names carry as much weight in the towing world as <strong>Blue Ox</strong>. <a href="/1459-blue-ox">Blue Ox</a> traces its manufacturing roots all the way back to 1925, when the parent company — Automatic Equipment Manufacturing — began building durable, purpose-driven equipment in Pender, Nebraska. Over the following decades, the brand evolved into one of the most recognized names in aftermarket towing, earning a loyal following among RV enthusiasts, weekend campers, and commercial towers alike.</p><p>What sets Blue Ox apart is a relentless focus on engineering products that are not only reliable but genuinely easy to use. Whether you're flat towing a car behind a Class A motorhome or hauling a loaded travel trailer across mountain passes, Blue Ox designs its products with real-world towing challenges in mind. The brand is known internationally for its tow bars and baseplates, sway control systems, and weight-distributing hitches — a product portfolio that continues to grow alongside customer needs.</p><h3>A Full Lineup Built for the Road Ahead</h3><p>At the heart of the Blue Ox catalog are its award-winning <a href="/1459-blue-ox-tow-bar-1200">tow bars</a>, which have become a benchmark for flat towing behind motorhomes. Models like the Avail and Ascent offer varying tow capacities and are engineered to work seamlessly with Blue Ox baseplates, giving drivers a complete and confidence-inspiring flat towing system.</p><p>For those towing heavier trailers and campers, Blue Ox's lineup of <a href="/1459-blue-ox-trailer-weight-distribution-kit-48263">trailer weight distribution kits</a> is equally impressive. The flagship SwayPro and TrackPro systems use spring bars and integrated sway control to distribute tongue weight evenly across the axles of both the tow vehicle and trailer — reducing rear sag, improving steering feel, and keeping sway in check even in crosswinds or on rough roads.</p><p>A properly matched <a href="/1459-blue-ox-trailer-hitch-1212">trailer hitch</a> is the foundation of any towing setup, and Blue Ox offers a range of hitch options designed to integrate tightly with their broader towing ecosystem. Completing the system, Blue Ox also produces <a href="/1459-blue-ox-trailer-wiring-adapter-connector-2632">trailer wiring adapter connectors</a> to ensure your brake lights, turn signals, and running lights communicate reliably between vehicles — an often-overlooked but critical part of safe towing. For rigs that need a bit more reach or clearance, <a href="/1459-blue-ox-trailer-hitch-receiver-extension-48970">trailer hitch receiver extensions</a> round out the lineup, helping dial in the perfect connection geometry.</p><h3>Why Towing Enthusiasts Choose Blue Ox</h3><ul style="list-style:disc"><li><strong>Decades of manufacturing heritage</strong> dating back to 1925 in Pender, Nebraska</li><li><strong>Award-winning tow bars</strong> with multiple capacity tiers to match any towing vehicle</li><li><strong>Integrated sway control</strong> technology built into weight distribution systems like the SwayPro</li><li><strong>Complete towing ecosystems</strong> — baseplates, tow bars, hitches, wiring, and accessories designed to work together</li><li><strong>Broad vehicle coverage</strong> with applications for virtually every flat-towable vehicle on the road</li><li><strong>Training and support</strong> through a network of certified dealers and installers across the U.S. and Canada</li></ul><p>Whether you're setting up your first flat towing rig or upgrading a long-haul trailer setup, Blue Ox delivers the hardware and expertise to do it right.</p>
