YOMILINK 8000 lb Trailer Jack Bolt-On, 28.6" Travel — Galvanized Heavy-Duty, 5-Position Adjustable

YOMILINK's 8000 lbs bolt-on trailer jack is a heavy-duty, side-mounted tongue jack with 28.6" vertical travel and a corrosion-resistant galvanized finish for reliable trailer lifting and stabilization.

This bolt-on/weld-on trailer jack is engineered to lift and stabilize trailers up to 8,000 pounds while offering a wide, adjustable height range to suit tall and low-profile trailers. Built from thick steel tubing with a protective galvanizing coating and an oversized base plate, it combines durability with user-friendly handling. The textured ergonomic grip and multi-level height settings make hitching, leveling and storage adjustments faster and safer for both occasional and frequent trailer users.

How much weight can this jack safely handle?

The YOMILINK trailer jack is rated for an 8,000-pound lifting capacity, making it suitable for most medium-duty utility, equipment, and travel trailers when used within its rated limits. Always check your trailer’s tongue weight and confirm useful load distribution before lifting.

• Official lift rating: 8,000 lbs (maximum)
• Side-mounted bolt-on or weld-on installation for secure attachment
• Designed for tongue loads consistent with the jack’s rating; not for full-vehicle lifting

What range of height adjustment and travel does it offer?

This jack provides a long travel span with vertical movement from approximately 4.5" to 33.4", and the threaded internal mechanism yields 28.6" of usable vertical travel. A five-position adjustable height system lets you choose the optimal working height for hitching, leveling, or stowing the jack.

• Lifting range: about 4.5" minimum to 33.4" maximum
• 28.6" of vertical travel for broad fit across trailer designs
• Five-level adjustment for finer height control

How is the jack built to resist corrosion and wear?

The main tube and components are heavy-duty steel with a galvanizing finish to protect against rust and corrosion in outdoor, marine, and road-salt environments. Structural design, including the oversized base plate, improves footprint stability and reduces wear on the mounting area.

• Heavy steel tubing construction for strength and longevity
• Galvanized coating to slow corrosion and surface degradation
• Oversized base plate disperses load and improves ground contact

How easy is it to operate and install?

The textured, elongated side handle gives more leverage and a secure grip than standard short flared handles, reducing effort during cranking. Installation is straightforward: bolt the side-mounted jack to the trailer tongue or weld it in place for a permanent mount. Standard mounting patterns and a bolt-on design make retrofit and replacement simple for most trailer owners.

• Ergonomic textured handle for improved grip and control
• Bolt-on or weld-on options to suit temporary or permanent installs
• Designed to fit common mounting configurations for easy replacement

Who is this for? The YOMILINK 8000 lbs trailer jack is aimed at trailer owners who need a robust, dependable tongue jack for mid-weight trailers — including equipment haulers, utility trailers, and some travel trailers — who want corrosion resistance, wide vertical travel, and easier cranking. It’s also a good choice for DIY installers and fleet operators who prefer bolt-on convenience or the option to weld for a permanent fit. As with any lifting equipment, ensure the jack’s rating matches your trailer’s tongue weight and follow all safe-installation practices.
