YOMILINK 8000 lb Bolt-On Trailer Jack 28.6 in Travel — Galvanized Side-Mount, 5-Position

The YOMILINK 8000 lbs bolt-on trailer jack is a heavy-duty, side-mount lifting solution offering 28.6" of vertical travel and a corrosion-resistant galvanized finish for dependable trailer support.

Built to handle large trailers, this bolt-on jack combines a high 8,000-pound capacity with multi-position height adjustment and an extended textured side handle to make hitching, leveling and stabilizing easier. The unit mounts to the trailer tongue by bolting or welding, and its oversized base plate plus sturdy steel construction are made for frequent use in outdoor conditions where rust resistance matters.

How much weight can this jack safely lift and support?

The jack is rated for an 8,000-pound load capacity, making it suitable for most heavy utility, travel and equipment trailers. Rating reflects static lifting capacity for the jack assembly when mounted according to instructions.

• 8,000 lbs maximum rated load
• Designed as a side-mounted, bolt-on (or weld-on) installation
• Oversized base plate distributes weight for stability

What range of height adjustment does the jack provide?

This model features multi-level adjustment with five selectable positions and a vertical travel range from 4.5 inches up to 33.4 inches. The wide travel span accommodates both low-profile trailers and taller setups without additional adapters.

• 5-position height adjustment for fine tuning
• Travel range: 4.5" to 33.4" for versatile clearance
• Adjustments made via the side-mounted crank for leverage

What materials and finishes are used to resist corrosion and wear?

The jack tube and components are made from heavy-duty steel and receive a galvanizing coating to protect against rust and environmental wear. The finish extends service life in wet or salty conditions and reduces long-term maintenance needs.

• Heavy-gauge steel construction for strength
• Galvanized coating for improved corrosion resistance
• Weldable or bolt-on design for secure attachment

How does the handle and base design improve usability?

The textured, elongated side handle gives more leverage and a more secure grip than standard flared handles, so you can raise or lower the trailer with less effort and better control. A generous, stable base plate keeps the jack from sinking into soft ground and provides a reliable contact surface when stationary.

• Textured long side handle for comfortable, controlled cranking
• Robust base plate for improved ground contact and stability
• Side-mounted orientation keeps tongue area accessible

Who this is for: The YOMILINK 8000 lbs bolt-on trailer jack is aimed at owners of heavier trailers—such as large utility trailers, travel trailers, small equipment haulers, and work trailers—who need a durable, rust-resistant lifting solution with wide vertical travel. It's a good fit for DIY installers and professional shops that prefer a bolt-on or weld-on mount, and for anyone wanting improved crank leverage and a stable base for frequent hitching, leveling, and storage.
