BIG RED Boat Trailer Jack ATR39001R-1 1000 lb Swing-Back Bolt-On with 6in Nylon Wheel, Zinc-Plated Steel

BIG RED ATR39001R-1 is a bolt-on, swing-back trailer jack with a 6" nylon wheel and 1,000 lb lift capacity for safely raising and maneuvering small boat and utility trailers.

This heavy-duty swivel tongue jack pairs corrosion-resistant zinc-plated steel construction with a compact 10-1/2" to 20-1/2" lift range, a convenient side-wind handle and a 360° rotating wheel mount so you can quickly raise, lower and steer your trailer at the dock, storage yard or campsite. It installs on 3"–5" tongues using the included bolt-on hardware and folds up parallel to the tongue for travel to keep the wheel out of the way.

How easy is this jack to install and remove?

Installation is straightforward: the jack ships with a bolt-on bracket and all necessary fasteners plus instructions. It mounts to standard 3"–5" trailer tongues and can be bolted or welded depending on your preference.

• Included bolt-on mounting hardware for quick assembly
• Fits 3" to 5" tongue widths without extra adapters
• Can be welded for permanent installation if desired
• Swings up parallel to tongue for travel clearance

What strength and durability features should I expect?

The ATR39001R-1 is built from galvanized, zinc-plated steel with a powder-coated finish to resist rust and wear in wet environments. Internal and external tube plating plus robust welds deliver rigidity while the 1,000 lb rating covers small boats, RV tongue loads and light utility trailers.

• Heavy-duty carbon steel body with zinc plating for corrosion resistance
• Powder-coated outer finish for extra durability in outdoor use
• Designed to handle 1,000 lb static load safely
• Side-wind handle with integrated grip for consistent operation

How does the 6" wheel perform on different surfaces?

The 6" nylon (PP) wheel provides a broad footprint to reduce sinking on soft ground and roll smoothly over gravel, grass and paved ramps. Its 360° swivel lets you pivot the trailer into tight spaces and maneuver by hand when needed.

• 6" PP wheel resists punctures and handles uneven terrain
• Wide surface area minimizes sinking in soft earth or sand
• 360° swivel function for easy lateral movement and positioning
• Wheel material resists abrasion from rocks and rough surfaces

What are the key dimensions and compatibility details?

The jack retracts to 10-1/2" and extends to 20-1/2", covering typical low- and mid-profile trailers. The design works with 3"–5" tongues and the swing-back bracket prevents damage to the wheel during towing by folding up parallel to the tongue.

• Retracted height: 10-1/2" (267 mm)
• Extended height: 20-1/2" (521 mm)
• Mounts to 3"–5" wide trailer tongues
• Includes a limited 1-year manufacturer warranty

Who is this for? The BIG RED ATR39001R-1 is aimed at boat owners, small trailer users and DIYers who need a compact, corrosion-resistant tongue jack that’s simple to install, offers smooth manual maneuvering and folds out of the way for travel. It’s well suited for launch-and-retrieve duties, light-duty utility trailers, and anyone who prefers a bolt-on jack with a durable nylon wheel and swivel action rather than a permanently mounted landing leg.
