YOMILINK 8000 lb Trailer Jack Bolt-On 28.6in Travel — Galvanized, Oversized Base Plate

YOMILINK's 8000 lbs bolt-on trailer jack delivers heavy-duty, corrosion-resistant lifting with 28.6" vertical travel for stable trailer leveling and hitching.

Built for trailers that demand strength and dependable adjustment, this side-mounted, bolt-on (or weldable) jack combines a high 8,000-pound capacity with a long lifting range and a textured ergonomic handle. Its galvanized steel construction and oversized base plate reduce rust and increase footprint stability so you can raise, lower, and secure your trailer on uneven surfaces.

How much weight can this jack safely lift and support?

The YOMILINK jack is rated for an 8,000-pound capacity, designed to handle the tongue loads and support needs of medium to heavy trailers. The heavy-duty steel tube construction and reinforced base are engineered to bear consistent load without deformation when properly installed.

• 8,000 lb rated lift capacity for trailer tongues and support
• Galvanized finish resists corrosion for long service life
• Oversized base plate increases ground contact and stability

What range of height adjustment does it offer and how is it operated?

This jack offers a vertical travel range from 4.5 inches up to 33.4 inches, giving five selectable height positions so you can match a variety of trailer heights. Operation uses a textured, extended side handle for easier winding and finer control when raising or lowering the trailer.

• 5-level adjustable height positions for flexible coupling and leveling
• 4.5" minimum to 33.4" maximum lifting reach for tall or low-profile trailers
• Long textured handle provides better grip and reduced hand fatigue

How is the jack mounted and how durable is the finish?

The jack is designed for side-mounted bolt-on installation and can also be welded in place for a permanent fit. The heavy-gauge steel tube is hot-dip or electro-galvanized (depending on model batch) to slow rust formation and withstand outdoor exposure.

• Bolt-on or weldable side-mount design for installation flexibility
• Heavy-duty steel construction resists bending under load
• Galvanized coating protects against corrosion and surface wear

What stability and safety features help keep a trailer secure?

Stability comes from a manufactured oversized base plate and sturdy welds that increase the footprint and prevent sinking on softer ground. The robust mechanical components and precise adjustment steps reduce the chance of sudden drops while you hitch or service the trailer.

• Large base plate spreads load to prevent sinking and rocking
• Secure multi-position locking for stable height selection
• Textured handle reduces slippage during crank operation

Who this is for: The YOMILINK 8000 lb bolt-on trailer jack suits boat trailers, utility trailers, car haulers, and others needing a rugged, long-travel tongue jack. It’s a practical upgrade for DIYers, fleet owners, and weekend haulers who want a corrosion-resistant, high-capacity jack that installs on the tongue and gives precise height control for safe hitching and storage.
