Kohree 8000 lb Manual Trailer Jack — Bolt-On Drop-Leg, 24.8–53.5" Adjustable, Galvanized Heavy-Duty

The Kohree 8000 lbs Manual Trailer Jack is a heavy-duty, bolt-on drop-leg tongue jack built to lift and stabilize trailers up to 8,000 pounds with a corrosion-resistant steel construction and an adjustable 24.8–53.5 inch range.

If you tow an RV, horse trailer, or utility trailer, you need a reliable tongue jack that’s simple to install, comfortable to crank, and durable in changing conditions. Kohree’s manual jack combines a thick-gauge galvanized outer tube, reinforced inner gearing, and an oversized foot plate so you can raise and lower trailers without wobble or premature wear. The unit bolts directly to trailer frames between 2" and 5", includes a removable non-slip handle for easier cranking, and features a grease fitting for routine maintenance.

How much weight can this jack handle and what protects it from wear?

The jack is rated for up to 8,000 pounds and uses heavy-gauge, high-strength steel components to resist bending under load. Protective galvanization and reinforced internal gears help prevent corrosion and gear wear that commonly cause failures.

• 8,000 lbs maximum load rating verified by construction specs
• Thickened galvanized tubes resist rust and mechanical wear
• Reinforced inner gear for smoother, longer-lasting operation
• Oversized foot plate distributes weight on soft or uneven ground

What mounting options and frame sizes are compatible?

This is a bolt-on design supplied with four long screws and two mounting brackets so you can attach it directly to most trailer frames. It’s intended for frames with material thicknesses and clearances corresponding to 2"–5" mounting locations.

• Bolt-on installation using included screws and mounting parts
• Fits trailer frames in the 2" to 5" range (measure before ordering)
• Designed for secure, vibration-resistant attachment to steel frames
• Quick installation when hardware is aligned and holes are pre-drilled

How adjustable is the jack and how does the handle improve usability?

The drop-leg jack offers five height positions spanning 24.8" to 53.5", so it accommodates a wide range of trailer tongues and ground clearances. The detachable side handle has a non-slip rubber texture and an extended length to reduce cranking effort and improve leverage.

• Five selectable height settings for flexible tongue clearance
• 24.8" minimum to 53.5" maximum reach for varied trailer types
• Detachable ergonomic rubber handle for easier, safer cranking
• Reduced effort during lift thanks to extended handle leverage

What maintenance is required to keep the jack working reliably?

Periodic lubrication and inspection are the main upkeep tasks. Kohree includes a grease fitting so you can re-lubricate the gear and internal components, and the galvanized finish reduces the frequency of corrosion-related maintenance.

• Grease fitting allows straightforward periodic lubrication
• Inspect mounting bolts and hardware for tightness before use
• Wipe and clean exposed surfaces after salty or muddy conditions
• Replace worn fasteners and check gear operation annually

Who is this for? The Kohree 8000 lbs Manual Trailer Jack is aimed at trailer owners who want a rugged, budget-conscious bolt-on solution for lifting and stabilizing mid- to heavy-duty trailers: RV owners, horse and livestock trailer haulers, landscape and utility trailer users, and anyone needing a reliable manual jack that tolerates rough terrain. If you need a powered or swivel-style jack, consider other models; if you want a durable, easy-to-service manual jack with wide height adjustability and a comfortable crank, this Kohree unit is a practical match.
