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

A heavy-duty, weld-on square trailer jack from TYT rated for 8,000 lbs tongue weight (7,000 lbs lift) that delivers 15 inches of vertical travel, a 13-inch adjustable drop leg, and a side-wind crank for reliable lifting and positioning.

This TYT square direct-weld trailer jack is built to give a sturdy, low-profile mounting solution for boats, campers, RVs and utility trailers. The design trades a bolt-on base for a permanent weld mount that resists side-loading and keeps the jack firmly attached to the tongue. With weather-resistant finishes, overlapping square tubes for added rigidity, and a removable drop leg, it combines strength with practical on-trailer convenience.

How strong is this jack and what weight can it handle?

The TYT jack is engineered to support heavy trailer tongues: it’s rated to handle up to 8,000 pounds tongue weight with a 7,000-pound safe lift capacity. The square outer and inner tubes overlap to increase structural capacity when fully extended, reducing flex under load.

• Rated tongue capacity: 8,000 lbs (7,000 lbs lift capacity)
• Outer tube diameter roughly 2.6 inches for added durability
• Heavy-gauge square construction resists side-loading better than round tube designs
• Net weight about 24.25 lbs for robust, weld-on installation

How much lift and adjustability does it provide?

This side-wind jack offers 15 inches of vertical lift using a hand crank, with total retracted and extended heights designed for typical trailer tongues. The included drop leg extends up to about 13 inches and secures with a pin and clip, enabling faster setup and added clearance without relocating the main jack tube.

• 15 inches of vertical travel from the inner tube
• Drop leg adjustable up to 13 inches with pin-and-clip retention
• Retracted overall height: ~24.25 inches; extended: ~39.25 inches
• Side-wind handle provides controlled, gradual lifting and lowering

What materials and finishes protect this jack from the elements?

The jack combines a zinc-plated inner tube with a weather-resistant coated outer tube to slow corrosion and extend service life in wet or dusty environments. The heavy-gauge square tubing and overlapping sections also minimize wear from repeated use while keeping moving parts better protected.

• Zinc inner tube for corrosion resistance on sliding surfaces
• Durable weather-resistant coating on the outer tube
• Heavy-gauge construction to withstand frequent service use
• Designed for long-term outdoor exposure on trailers and RVs

Why choose a weld-on square jack instead of a bolt-on round jack?

A weld-on square jack creates a rigid, permanent mounting point that is less likely to shift under side loads and heavy use. Square tubing resists twisting better than round jacks, which is useful when lifting from the tongue side for wheel changes or bearing work.

• Welded mount prevents movement that can loosen bolt-on bases
• Square tube geometry adds resistance to side forces and torsion
• Overlapping tubes increase strength when jack is extended
• Drop leg allows quick height adjustments without altering the main jack position

Who this product is for: The TYT 8000 lbs square direct-weld trailer jack is best suited to owners of boats, travel trailers, RVs, campers and heavy utility trailers who want a permanent, heavy-duty lifting solution. It’s ideal for users who perform roadside or yard service, need reliable side-lifting capacity for wheel or bearing maintenance, or prefer the stability of a welded mount over bolt-on alternatives. If you need a corrosion-resistant, high-capacity jack with a quick-adjust drop leg and controlled side-wind operation, this model is designed to meet those needs.
