Ultra-Fab Wheel Stops & Chocks
When it comes to eliminating unwanted movement in parked RVs and trailers, Ultra-Fab has built a reputation for engineering some of the most innovative wheel stops and chocks in the industry. Since 1958, this American-owned manufacturer has specialized in lifting, leveling, and stabilizing solutions that address the real-world challenges faced by RV owners and trailer enthusiasts.
The Ultra-Fab Approach to Wheel Stabilization
Ultra-Fab's wheel chocks are specifically designed to limit front-to-back motion on parked tandem-axle trailers, distinguishing them from traditional wedge-style chocks that simply prevent rolling. The company's signature product lines—including the Chock and Lock series and the Super Grip Chock family—work by anchoring opposing wheels against each other, using the tandem axle configuration itself as the stabilizing force.
Innovative Product Technologies
Ultra-Fab's wheel chocks eliminate front-to-back rocking and most side-to-side motion by locking tandem wheels firmly in place, with self-adjusting louvers that grip tire treads securely. This patented louver system represents a significant advancement over competitors, as the pivoting louvers allow each chock to get a stronger grip by swiveling to conform to the exact curve of tires.
The company offers three main expansion ranges to accommodate different trailer configurations: the standard Chock and Lock models expand from 1.5 to 5.25 inches, the Super Grip Chock adjusts for tandem-axle trailers with up to 10.5-inch wheel spacing, and the Super Grip Chock XL handles wheel spacing up to 17 inches, making Ultra-Fab one of the few manufacturers to serve wide-track modern RVs.
Built for Durability and Security
Ultra-Fab constructs their wheel chocks from high-strength steel with corrosion-resistant zinc plating for long-lasting durability in all weather conditions. The company addresses a common weakness in competitor designs with their unique handle secured at both ends to practically eliminate slippage while mounting. Additionally, Ultra-Fab is the first and only brand to include padlocks with each chock in the package, backed by a lifetime warranty.
Ease of Use and Practical Design
The E-Z Grip Handle provides superior leverage for quick installation and removal, collapsing flat for compact storage when not in use. Each stabilizer includes a ratcheting wrench, and using chocks on one side removes an estimated 85% of motion, while using them on both sides removes approximately 95% of unwanted movement. This makes Ultra-Fab wheel chocks particularly valuable for full-time RVers and long-term campers who need maximum stability.
Whether you're securing a lightweight travel trailer or a heavy fifth wheel, Ultra-Fab's comprehensive range of wheel stops and chocks delivers the engineering innovation and build quality that has made Ultra-Fab a household name among RV owners and dealers since 1958.
