TYT Square Weld-On Trailer Jack 15in Lift, 13in Adjustable Drop Leg — 8,000 lb Capacity, Side-Wind Black

The TYT 8000lbs Square Direct Weld Heavy Duty Trailer Jack is a weld-on side-wind jack with a 15-inch lift and 13-inch adjustable drop leg designed to make raising and stabilizing boats, RVs, campers, and utility trailers faster and more secure.

Built for rugged use and side mounting, this square tube trailer jack combines heavy-gauge steel with overlapping inner and outer tubes for extra rigidity when extended. It offers corrosion-resistant finishes, a convenient side-wind handle, and a pinned drop leg so you can quickly change lift height without crawling under the trailer. The design balances high tongue-weight capacity with compact retracted dimensions so it fits most welded trailer tongues while still delivering dependable lift performance.

How much weight can this jack safely handle?

This TYT square trailer jack is rated for an 8,000-pound tongue weight (with a 7,000-pound practical lift capacity), giving it the strength needed for large boats, travel trailers, and heavier utility loads. Ratings reflect the design capacity for supporting and lifting the trailer tongue when used as intended—welded to the trailer frame and operated from the sidewind handle.

• Maximum rated tongue weight: 8,000 lbs
• Practical lift capacity: approximately 7,000 lbs
• Outer tube diameter: 2.6 inches for added stiffness
• GW (gross weight shipped): 24.25 lbs

How far does the jack raise and what are the dimensions?

The jack provides 15 inches of vertical lift between its retracted and fully extended positions, with a total retracted height around 24.25 inches and fully extended height near 39.25 inches. A 13-inch adjustable drop leg increases clearance for larger tires or to reduce crank time when raising the trailer.

• Standard lift range: 15 inches
• Retracted total height: 24.25 inches
• Extended total height: 39.25 inches
• Adjustable drop leg: 13 inches with pin-and-clip retention

What materials and finishes protect the jack from the elements?

The TYT jack uses a weather-resistant coating on the outer tube and zinc-plated inner tubing to resist rust and abrasion from road grime, salt, and moisture. Heavy-gauge steel construction and the square profile improve side-loading strength while the coatings extend service life in outdoor and marine environments.

• Outer tube: weather-resistant black coating for abrasion resistance
• Inner tube: zinc-plated finish for corrosion protection
• Heavy-gauge steel and overlapping tubes for structural durability
• Designed for long-term outdoor exposure when properly mounted

How is the jack mounted and operated safely?

This model is intended to be welded directly to the trailer tongue for a very robust connection that resists side-loading and torsion. Operation uses the sidewind handle to raise and lower, and the drop leg locks with a pin and clip so you can set the desired working height quickly and reliably.

• Mounting method: direct weld-on to trailer tongue
• Operation: side-wind crank for controlled lifting and lowering
• Drop leg: pin-and-clip locking for adjustable support height
• Best practice: weld by a qualified welder and inspect mounts periodically

Who is this for: The TYT 8000lbs Square Direct Weld Heavy Duty Trailer Jack is aimed at owners of boats, RVs, campers, and utility trailers who need a heavy-duty weld-on jack with strong side-load resistance and a fast drop-leg option. It suits DIYers and professionals who want a durable, corrosion-resistant lifting solution that keeps trailers stable during maintenance, wheel changes, hitching, and storage.
