<h3>About Blue Ox Towing Products</h3><p>Few names carry as much weight in the towing world as <strong>Blue Ox</strong>. Rooted in a manufacturing heritage that stretches back to 1925 in Pender, Nebraska, Blue Ox has spent a century refining the art of hitching up and heading out. <a href="/1459-blue-ox">Blue Ox</a> is recognized internationally for producing towing equipment that is as dependable on mountain passes as it is on open plains — built for RVers, truck owners, and weekend adventurers alike.</p><p>The company began entering the recreational towing market in the early 1980s and, through strategic growth, evolved into a premier aftermarket towing manufacturer. Today, Blue Ox engineers and produces a comprehensive lineup that covers virtually every towing scenario on the road. Whether you're flat-towing a vehicle behind a motorhome or hauling a loaded travel trailer down the interstate, there's a Blue Ox product designed specifically for the task.</p><h3>A Complete Towing Ecosystem</h3><p>What sets Blue Ox apart is its commitment to building an integrated towing system rather than one-off components. At the heart of their lineup are their award-winning <a href="/1459-blue-ox-tow-bar-1200">tow bars</a>, including the popular Alpha and Avail models, which have earned a loyal following among flat-towing enthusiasts for their solid construction and easy setup. These work in concert with vehicle-specific baseplates to create a seamless connection between motorhome and towed vehicle.</p><p>For drivers pulling conventional trailers, Blue Ox's <a href="/1459-blue-ox-trailer-weight-distribution-kit-48263">trailer weight distribution kits</a> are a standout solution. The flagship SwayPro and TrackPro systems go beyond simple weight redistribution — they actively manage trailer sway using pre-loaded spring bars that counter the forces of crosswinds, rough roads, and passing trucks. The result is a dramatically more stable and controlled towing experience.</p><p>A complete towing setup also depends on solid attachment points and reliable electrical connections. Blue Ox's <a href="/1459-blue-ox-trailer-hitch-1212">trailer hitches</a> provide the foundational connection between tow vehicle and trailer, engineered to handle everything from light-duty loads to heavy commercial hauls. Their <a href="/1459-blue-ox-trailer-wiring-adapter-connector-2632">trailer wiring adapter connectors</a> ensure your brake lights, turn signals, and running lights communicate flawlessly between vehicles — an essential safety element often overlooked until something goes wrong. For situations where a standard hitch receiver isn't quite in the right position, Blue Ox <a href="/1459-blue-ox-trailer-hitch-receiver-extension-48970">trailer hitch receiver extensions</a> provide the necessary adjustment to achieve proper tow bar or hitch alignment.</p><h3>Built on a Century of Trust</h3><p>Blue Ox maintains a national network of trained and certified dealers, and even runs an RV park adjacent to its Nebraska factory — hosting traveling customers and conducting installation training sessions across the U.S. and Canada throughout the year. This dedication to the customer experience, from product design through post-sale support, reflects a brand that understands towing isn't just a mechanical exercise. It's about the confidence to go wherever the road leads.</p><ul><li>Extensive product lineup covering flat towing, trailer towing, and 5th wheel applications</li><li>Flagship SwayPro and TrackPro weight distribution systems with integrated sway control</li><li>Award-winning tow bar models engineered for quick connection and rugged durability</li><li>Full ecosystem of wiring, receiver extensions, and hitch accessories</li><li>Certified dealer and installer network spanning the U.S. and Canada</li></ul>

Product Details

The Blue Ox BXW4057 is a replacement spring bar kit designed specifically for Blue Ox 2-Point weight distribution hitch systems. This kit allows you to replace worn spring bars or adjust your system's tongue weight rating to 600 pounds, making it ideal for trailers with 400-600 lbs of tongue weight capacity.

Key Features:

  • Round spring bars rated for 600 lb tongue weight capacity
  • Compatible with Blue Ox 2-Point weight distribution hitch systems
  • Powder-coated steel construction for durability and corrosion resistance
  • Spring bars flex appropriately for a controlled, even ride
  • Helps evenly distribute trailer tongue weight across tow vehicle and trailer axles
  • Works with rotating latches and L-bracket mounting system
  • Made in the USA

This replacement kit includes both spring bars needed for your 2-Point weight distribution system. The round spring bars insert into the weight distribution hitch head and work with the system's caster effect to provide sway control and improved towing stability. Note that L-brackets, retaining pins, and other mounting hardware are sold separately.
