TOWKING 2000 lb Boat Trailer Jack, 10" Lift Bolt-On for 3x5 Frames — Galvanized with Wheel

The TOWKING 2000 lbs Upgraded Boat Trailer Jack is a bolt-on, galvanized trailer jack that lifts up to 2000 lbs with a 10" adjustable travel for secure launching, loading and storage.

Built for boaters and trailer owners who need a dependable, corrosion-resistant jack, this TOWKING model combines a reinforced wheel, greaseable components and SAE-compliant construction to handle medium to large trailers. With a compact bolt-on design that fits 3" x 5" frames, the jack gives a 12" retracted height and 22" extended height so you can match common trailer tongue clearances without welding or complex adapters.

How much weight can this trailer jack support and what does that mean in practice?

This jack is rated for a 2000 lb load capacity, which covers many single-axle and light tandem-axle boat trailers and utility trailers. The capacity rating describes the static vertical load the jack can safely support when properly installed and used within the travel range.

• 2000 lbs rated vertical capacity for tongue support
• Suitable for medium to large boats depending on trailer setup
• Designed for static lifting, not for lifting the trailer from an unstable surface

What are the physical dimensions and adjustment range of the jack?

This TOWKING jack measures 12" when retracted and extends to 22", delivering a 10" useful travel span that accommodates common trailer heights without extra parts. The bolt-on bracket is sized for 3" x 5" frames, simplifying installation onto many commercial trailer frames.

• 12" retracted height, 22" extended height — 10" movement
• Bolt-on design fits 3" x 5" frame cutouts or brackets
• Compact footprint keeps the jack out of the way when stowed

What durability and maintenance features help this jack last outdoors?

The jack uses high-strength steel with a galvanized finish to resist corrosion in marine environments, while the upgraded PP wheel and reinforced spoke axle give smoother rolling under load. A grease fitting and included mounting hardware make routine maintenance and installation straightforward.

• Galvanized steel finish for weather and rust protection
• Durable PP wheel with reinforced axle for smoother movement
• Grease fitting for periodic lubrication to extend service life

How easy is installation and everyday use?

Installation is bolt-on with hardware included for standard 3" x 5" frames — no welding required. The handle strap secures the winding handle for transport, and the wheel helps maneuver the trailer when the jack is lowered to the ground.

• Comes with installation hardware for a simpler fit-up
• Handle strap secures the crank during travel or storage
• Wheel enables manual maneuvering of the trailer on level surfaces

Who this is for: boat owners, RV and utility trailer operators, fishing and watersports enthusiasts, and any trailer user looking for a bolt-on jack with a 2000 lb capacity, corrosion resistance and easy maintenance. If you need reliable tongue support, smoother wheel movement under load and a straightforward bolt-on installation for a 3" x 5" frame, the TOWKING 2000 lbs Upgraded Boat Trailer Jack is engineered to provide those capabilities without complex modification.
