SEACHOICE Heavy Duty Trailer Jack Fixed-Mount Drop Leg 28.6in Lift, 2,500 lb Capacity

The Seachoice Heavy Duty Trailer Jack is a bolt-on, fixed-mount drop-leg jack that delivers up to 2,500 lb capacity and 28.6 inches of smooth lift for trailers with frames up to 3" x 5".

If you tow boats, ATVs, or heavy cargo, a dependable trailer jack makes hooking up and leveling faster and safer. This Seachoice model is built for demanding trailer jobs: it mounts securely to common trailer frames, uses a twist-handle crank for controlled lifting and lowering, and includes the hardware needed for installation. Its drop-leg design keeps the jack compact while providing a long reach when you need to raise the trailer high enough for hitching or maintenance.

How does this jack handle heavy loads and long lifts?

The jack is rated to support up to 2,500 pounds, giving you enough capacity for many boats, utility trailers, and smaller RV or equipment loads. With 28.6 inches of lift, it reaches high enough to clear couplers and allow for trailer alignment. The internal gearing and twist-handle operation are optimized for consistent, controlled movement under load.

• Maximum capacity: 2,500 lb for safe single-point lifting
• 28.6 inches of vertical travel for generous clearance
• Twist-handle crank for smooth, steady operation
• Designed for continuous use in towing and storage tasks

What mounting options and dimensions do I need to know?

This is a fixed, bolt-on style jack intended for trailer frames up to 3" x 5". The unit ships with all required mounting hardware so you can attach it directly to compatible frame rails. Because it’s fixed-mount, it stays permanently attached to the trailer for reliable support when parked or being serviced.

• Fixed-mount bolt-on installation for secure attachment
• Compatible with trailer frames up to 3" x 5" cross-section
• Includes mounting hardware for a complete install
• Manufacturer part number: 50-52051 for ordering and replacement

How does the drop-leg design benefit everyday towing tasks?

The drop leg keeps the foot of the jack low and compact when stowed, then provides extended reach when lowered — ideal for uneven terrain or higher trailer couplers. The design reduces bulk while giving you the lift distance needed to hitch, level, or perform maintenance without additional jacks. It’s a practical balance of portability and lifting power for routine trailer use.

• Drop-leg profile for compact storage and long reach when needed
• Reduces need for supplemental jacks during hitching or repairs
• Stable base contact to minimize rocking while supporting load
• Good for trailers parked on slopes or rough ground

If you want simple bolt-on installation, substantial lifting range, and a 2,500 lb working capacity without buying a hydraulic or swing-away system, this jack is a practical and durable choice. Seachoice’s marine-focused design and included hardware make it especially suited to trailer owners who value reliability and components built for towing environments.
