Dnigh 6000 lb A-Frame Trailer Jack — 9"–40.5" Adjustable, Manual or 20–24V Drill Drive, Corrosion-Resistant

The Dnigh 6000LBS A-Frame Trailer Jack is a heavy-duty, corrosion-resistant trailer jack that lifts and levels A-frame trailers manually or with a 20–24V drill for fast, reliable hitching.

Whether you're pairing up a loaded utility trailer, horse trailer, or large RV, this Dnigh trailer jack is engineered to make trailer hookup and stabilization quicker and more dependable. Built from high-tensile alloy steel with a powder-coated finish and a 6,000 lb stationary capacity, the jack combines robust strength with versatile operation: use the top-wind crank for hand control or attach a 20–24V drill for fast power-assisted raising and lowering. The design emphasizes durability, straightforward installation, and a wide 9" to 40.5" adjustable range so you can get the trailer level on uneven ground without fuss.

How does the Dnigh jack make towing hookups faster and easier?

The jack accepts both manual cranking and drill-driven operation, letting you speed up the process when time matters. The top-wind handle provides smooth gear action, while the drill adapter turns repetitive lifting into a one-handed task.

• 20–24V drill-compatible drive for quick raising/lowering
• Top-wind crank for controlled, manual adjustment
• Fast, consistent gear engagement reduces effort and time

Can it handle heavy trailers and uneven surfaces?

Yes — the Dnigh jack is rated to support up to 6,000 lbs when stationary, making it suitable for large RVs, horse trailers and heavily loaded utility trailers. The multi-position height range helps you achieve a level setup even on sloped or irregular ground.

• 6,000 lb stationary capacity for high-load stability
• 9" to 40.5" adjustable height to match most A-frame hitches
• Multi-position leveling reduces tilt for safer coupling and loading

How durable is the construction for all-season use?

Dnigh uses high-tensile carbon alloy steel and a corrosion-resistant powder coating to resist rust and wear from road salt, moisture, and sun exposure. The build is intended for long-term service across seasons with minimal maintenance.

• High-tensile alloy steel body for strength and rigidity
• Powder-coated finish for corrosion and abrasion resistance
• Designed to withstand outdoor storage and frequent use

What comes with the jack and how easy is installation?

The package includes all required mounting hardware and is engineered for a straightforward install, often completed in minutes without special tools. Clear attachment points and a compact footprint help simplify fitting to standard A-frame tongues.

• All necessary hardware included for mounting to A-frame tongues
• Tool-free or minimal-tool assembly for most users
• Compact design keeps the jack out of the way when towing

Who is this for? The Dnigh 6000LBS A-Frame Trailer Jack is aimed at trailer owners who need a dependable, heavy-capacity jack that combines power-assisted convenience with rugged longevity. If you own a large RV, horse trailer, or frequently loaded utility trailer and want an easy-to-install jack that speeds hookups, resists the elements, and reduces physical strain, this model delivers practical value. It’s also a good choice for fleet managers, seasonal travelers, and anyone replacing an underpowered or corroded tongue jack.
