<h3>Ultra-Fab: Lifting, Leveling &amp; Stabilizing RVs Since 1958</h3><p>When it comes to keeping an RV safe, steady, and level at the campsite, few names carry as much weight as <strong>Ultra-Fab Products</strong>. Founded in 1958 and headquartered in Elkhart, Indiana — widely regarded as the RV capital of the world — Ultra-Fab has spent more than six decades engineering solutions that take the hassle out of setting up camp. Their product lineup focuses on one core mission: making it easier to lift, level, and stabilize any towable RV, from lightweight pop-ups to heavy fifth wheels.</p><h3>A Legacy Built on Quality and Innovation</h3><p>Ultra-Fab's reputation rests on a combination of rigorous product testing, all-steel construction, and a drive to innovate. The brand is perhaps best known for its flagship Phoenix series, which Ultra-Fab itself bills as home to the <em>&quot;Fastest Jack on Earth.&quot;</em> These electric tongue jacks feature push-button operation, dual memory settings for fast hook-up, and water-resistant motor housings — details that reflect the brand's commitment to building products that perform reliably in real-world conditions, season after season.</p><p>Their <a href="/7625-ultra-fab-tongue-jacks-201082">Tongue Jacks</a> lineup spans both electric and manual configurations, with capacities ranging from 1,000 lbs up to 5,500 lbs to suit trailers of all sizes. Whether you need a basic side-wind manual unit for a utility trailer or a high-speed electric A-frame jack for a full-size travel trailer, Ultra-Fab offers an option engineered for the task.</p><h3>Jacks for Every Application</h3><p>Beyond tongue jacks, Ultra-Fab produces a wide range of <a href="/7625-ultra-fab-jack-14315">stabilizing and leveling jacks</a> designed to eliminate the rocking and swaying that can make life inside a parked trailer uncomfortable. Their scissor jacks, for example, feature a double-nut design that allows the jack to travel twice as far per rotation — a clever engineering touch that dramatically speeds up setup and teardown. Models like the PowerTwin II go a step further, spanning the full width of the RV frame to eliminate both front-to-back and side-to-side motion simultaneously, with up to 6,000 lbs of lifting capacity per leg.</p><p>Rounding out their catalog, Ultra-Fab's <a href="/7625-ultra-fab-trailer-parts-accessories-201094">Trailer Parts &amp; Accessories</a> selection gives owners everything they need to maintain, upgrade, and protect their jacking systems. From replacement caster wheels and footplates to weatherproof jack covers and slide-out supports, these accessories help extend the life of your equipment and keep your rig performing at its best.</p><h3>Why RV Owners Trust Ultra-Fab</h3><p>Ultra-Fab products are distributed through an extensive network of RV dealers across the United States, making them accessible whether you're shopping at your local RV dealership or online. The brand backs many of its products with industry-leading warranties — including lifetime coverage on select scissor jacks — a clear signal of confidence in their own manufacturing standards. For anyone serious about RV ownership, Ultra-Fab represents a trusted, time-tested partner for keeping adventures safe and comfortable from the moment you pull into camp.</p>

Product Details

The Ultra-Fab 21-001080 Chock and Lock XL is a professional-grade wheel stabilizer designed to eliminate front-to-back rocking motion on tandem axle RV trailers and fifth wheels. This innovative stabilizer works by anchoring the opposing wheels of tandem axles, causing the trailer wheels to work against each other to arrest any motion regardless of ground surface or slope.

Key Features:

  • Heavy gauge all steel construction with corrosion resistant zinc plating
  • One-piece design collapses to 4.25 inches and expands up to 10 inches
  • Fits wheel spacing between 4.5 and 10 inches
  • Easy to use lever operation with E-Z grip handle
  • Lockable design to minimize theft (padlock not included)
  • Super grip tire louvers reduce slip

This XL model provides superior stabilization for larger RVs with wider wheel spacing. Simply place the chock between your tandem tires, expand using the threaded rod adjustment, and press the handle down to lock it firmly in place. The unit stays compressed between your tires to eliminate movement while parked, providing a stable platform for camping or storage.
