TYT 8000 lb Square Weld-On Trailer Jack — 15" Side-Wind Lift with 13" Adjustable Drop Leg, Corrosion-Resistant

TYT's 8000 lbs square direct-weld trailer jack is a heavy-duty, side-wind lift with a 15" travel and a 13" adjustable drop leg for secure, corrosion-resistant support on boats, campers, RVs and utility trailers.

This welded-on square trailer jack from TYT combines a robust square-tube design with a side wind screw and an adjustable drop leg so you can raise or stabilize a trailer quickly and reliably. Engineered for higher tongue loads, the unit yields a compact retracted height and extended reach with overlapping outer and inner tubes for added rigidity. The finish and zinc-plated inner tube help resist weathering so it stays dependable through wet and dusty conditions.

How much weight can this jack safely handle?

The jack is rated to support an 8,000 lb trailer tongue weight and has a 7,000 lb lifting capacity—sized for heavier boats, RVs, and utility trailers. Ratings refer to tongue weight and lifting capability, not overall trailer GVW.

• 8,000 lb tongue weight rating
• 7,000 lb lifting capacity
• Suitable for large campers, boat trailers, and car haulers

What are the height and adjustment options?

The jack offers 15 inches of vertical travel operated by a side-wind handle. It measures about 24.25 inches when retracted and reaches roughly 39.25 inches when fully extended, and includes a 13-inch adjustable drop leg secured with a pin and clip for additional lift or leveling.

• 15" maximum lift (vertical travel)
• 24.25" retracted height; 39.25" extended height
• 13" adjustable drop leg with pin-and-clip retention

How durable is the construction and finish?

The square, heavy-gauge tube construction plus overlapping inner and outer tubes improve side-load strength and reduce flex when extended. TYT applied a weather-resistant coating to the outer tube and a zinc finish to the inner tube to limit corrosion from water, dirt, and road grime.

• Square tube design resists side loading better than round jacks
• Overlapping tubes add structural support at full extension
• Weather-resistant outer coating and zinc inner tube for corrosion resistance

How is the jack mounted and what maintenance is needed?

This model is intended for direct-weld attachment to the trailer tongue, creating a permanent, robust mount ideal for side lifting during wheel changes or bearing work. Routine greasing of the screw and periodic inspection of welds and fasteners will keep the jack operating smoothly for years.

• Weld-on installation for secure, low-profile mounting
• Side-wind screw requires occasional lubrication
• Inspect welds, pin, and finish periodically for safety

Who is this for? The TYT 8000 lbs square direct-weld jack is aimed at owners of larger trailers—boat trailers, travel trailers, RVs and heavy-duty utility rigs—who prefer a permanently mounted, side-wind lifting solution with extra side-load strength. If you need a corrosion-resistant jack with a significant lift range and a removable drop leg for added clearance or leveling, this model provides a durable, installation-ready option for professional mechanics, DIYers, and frequent tow vehicle users alike.
