MaxxHaul 70149 Trailer Jack
The MaxxHaul 70149 is a bolt-on trailer jack with an 11-1/2″ lift designed for utility and boat trailers. The swing-back design allows the jack to move out of the way when not in use, enabling you to operate the trailer without removing the jack. Its heavy-duty locking pin secures the jack in horizontal or vertical positions for stability during operation and storage. Best for trailers that require a reliable, space-saving jacking solution with straightforward installation.
Who it’s best for: boat trailer owners who want a compact, easy-to-store jack that still provides substantial lift and a secure lock. Why selected: its swing-back feature minimizes obstructions during towing and launching, improving maneuverability at ramps. Caution: installation is bolt-on, which may require basic hardware compatibility checks on non-standard frames.
Jeremywell Jack Boat RV Swing Away
The Jeremywell trailer jack offers a 1,000 lb lift capacity with a galvanized alloy steel build designed to resist corrosion. It features an ergonomic sidewind handle to ease cranking, providing comfortable operation up to a 10″ lift. Retraction length is 12.5″, extending to 22.5″ when raised. Best for lighter to mid-weight trailers needing a robust, corrosion-resistant jack with an ergonomic feel. Choose this if you prioritize comfort and resistance to marine environments. Caution: lower capacity than some 1,500 lb models may limit use with very heavy loads.
Trimax TH6 Swing-Away Trailer Lock
The Trimax TH6 is a premium receiver lock rather than a traditional jack. While it’s listed here as a swing-away option, it emphasizes security for trailer components and helps deter theft by securing the tongue area when parked. It’s a compact item with a lightweight profile, ideal for trailers that require added lock protection for travel or storage. Best for security-minded users who want to complement a swing-away jack with a strong lock. Caution: not a direct lifting jack; pairing with a separate swing-away jack is necessary for lifting tasks.
ONLYLIDA Folding Trailer Tongue Kit
The ONLYLIDA Folding Trailer Tongue Kit is a heavy-duty hinge designed to support an 11,000 lb towing capacity, suitable for large RVs and heavy marine trailers. It uses forged steel with a zinc finish for corrosion resistance and features bolt-on stability for solid mounting. Best for heavy trailers where a robust hinge extension helps with storage and quick setup. Caution: designed for specific tongue dimensions; verify beam compatibility before purchase.
Dutton-Lainson Swivel Marine Tongue Jack
The Dutton-Lainson Swivel Marine Tongue Jack features a rust-resistant zinc TUFFPLATE finish and a 1,000 lb capacity, with 10″ of travel and a 6″ heavy wheel. The swivel design offers 360-degree rotation for easier boat positioning and stowed positioning. Best for frequent launch scenarios where easy maneuverability is valued. Caution: older vehicles or non-marine environments might benefit from newer corrosion-resistant models.
Buying Guide: Swing-Away Boat Trailer Jacks
What capacity should I choose?
Capacity matters based on trailer weight and tongue weight. Most boat trailers fall in the 1,000–1,500 lb range. Choose higher capacity if you frequently load heavy boats or carry additional gear. A higher capacity provides greater stability and reduces the risk of bending or failing under load.
Swing-away vs. side-wind: which design fits my trailer?
Swing-away designs move the jack out of the way for towing and storage, improving clearance and maneuverability. Side-wind jacks operate from the side of the tongue and can offer ergonomic cranking with less lifting effort. For limited storage or frequent launching, swing-away with a space-saving profile is often preferable.
Locking mechanisms: how important are they?
A robust locking pin or integrated locking system is crucial for preventing accidental collapse during loading or travel. Look for jacks with a positive locking mechanism in both horizontal and vertical positions. This adds stability when the jack is in use and when stowed.
Materials and corrosion resistance: where will you use it?
Marine environments demand rust-resistant finishes like zinc TUFFPLATE or galvanized steel. If you frequently launch from saltwater ramps, prioritize corrosion resistance to extend the life of the jack and its moving parts.
Install and compatibility considerations
Bolt-on jacks require compatible trailer frames and mounting holes. Verify bolt pattern, frame thickness, and clearance around tires and fenders before purchase. Some models come with adjustable mounting plates to fit a range of trailers.
Maintenance and longevity
Regular lubrication of the crank and swivel components extends life. Inspect locking pins for wear and replace if they become loose. Clean off salt spray and rinse after exposure to sea air to protect metal surfaces.
