TOWKING 5000 lb Side Wind A-Frame Trailer Jack 15" Lift — Powder-Coated Steel, Drop Leg Option

The TOWKING 5000 lbs 15" Side Wind A-Frame Trailer Jack is a heavy-duty, corrosion-resistant tongue jack that lifts trailers up to 5000 lbs with a 15" travel range and optional drop leg for extra height.

This side-wind trailer jack is built for boat trailers, campers, and larger utility trailers that need dependable lifting power and weatherproof durability. Constructed from high-strength steel with a powder-coated finish and SAE-compliant manufacturing, it combines robust load capacity with straightforward manual operation. The unit retracts to 8" and extends to 23"; adding the 10" drop leg gives even more clearance for hitching or leveling on uneven ground.

How much weight can this jack reliably support?

The TOWKING jack is rated for a 5000-pound static load, making it suitable for many heavier trailers and recreational vehicles. This rating reflects the tongue load the jack can hold when properly mounted on an A-frame or straight tongue setup.

• 5000 lbs load capacity for heavy-duty applications.
• Suitable for larger RVs, boats, and cargo trailers when installed correctly.
• Manufactured to SAE standards for consistent quality and safety.

What range of height adjustment does the 15" lift provide?

The jack offers a 15" movement range — it sits at 8" when fully retracted and reaches 23" at full extension. If you need more rise without cranking, the detachable drop leg adds an extra 10" of instant height adjustment.

• 8" retracted height and 23" extended height for flexible hitching positions.
• Removable drop leg adds 10" of quick height increase.
• Manual side-wind handle enables precise, controllable lifting.

How does it hold up outdoors and in coastal environments?

The jack's exterior receives a powder-coated treatment that protects the underlying high-strength steel from corrosion and abrasion. While no finish is invulnerable, the coating significantly extends service life compared with bare metal and reduces maintenance frequency.

• Powder-coated surface resists rust and weathering.
• High-strength steel spine for structural longevity.
• Recommended periodic inspections and touch-ups in harsh marine conditions.

Is installation complicated and what maintenance is required?

Installation is straightforward for anyone familiar with trailer hardware: mount to the A-frame with the correct bolts and ensure the jack is aligned for smooth operation. Routine maintenance is minimal — keep moving parts lubricated, check fasteners, and rinse off salt or heavy grime after marine use.

• Mounts to standard A-frame tongues using appropriate hardware.
• Keep the screw thread and pivot points greased for smooth winding.
• Inspect fasteners and finish periodically; rinse saltwater-exposed units.

Who is this for? The TOWKING 5000 lb 15" Side Wind Trailer Jack is designed for trailer owners who need a rugged, manually operated lifting solution with extra height options. Ideal for RV and boat owners, landscapers, and small fleet operators who prefer a dependable mechanical jack over powered alternatives. It’s a good fit when load capacity, corrosion resistance, and SAE-grade construction are priorities rather than automated lifting convenience.
