NBJINGYI 8,000 lb Heavy Duty Square Trailer Jack – 28" Lift Range, 360° Swivel, Sidewind Crank, 4x4 Footplate

Overview of NBJINGYI 8,000 lb Trailer Jack

The NBJINGYI 8,000 lb Heavy Duty Square Trailer Jack is designed to provide reliable, long-lasting support for demanding trailers. Built with a 2.5" square tube, this jack delivers solid side-load strength and stability, making it a practical choice for heavy RVs, utility trailers, and equipment haulers. With up to 8,000 lbs of load capacity and about 7,000 lbs of lifting power, you gain sturdy leverage whether you’re parking, loading, or leveling on the go. The combination of rugged construction and thoughtful engineering aims to reduce the effort needed when handling a fully loaded trailer, while keeping the experience predictable and controlled.

360° Swivel Pipe Mount for Flexible Positioning

The rugged swivel bracket allows full 360-degree rotation, so you can tuck the jack parallel to the trailer frame during transport for maximum ground clearance. A heavy-duty positive-lock pin provides secure, rattle-free operation, supporting a calm encounter with varied terrains and weather conditions.

Impressive 28" Lift Range for Varied Terrain

Achieve precise leveling with a generous 28-inch vertical adjustment. The jack pairs smooth screw travel with a multi-position adjustable leg, enabling quick adaptation to different truck heights and uneven job sites or campground surfaces without guesswork.

Effortless Operation and Easy Maintenance

The ergonomic sidewind handle is paired with a grease zerk for straightforward lubrication. A precision-geared internal system ensures smooth, low-friction lifting, reducing physical effort when the trailer is fully loaded and resisting wear over time.

All-Weather Protection and Stability

A premium black E-coat finish combined with zinc plating protects against corrosion from road salt, water, and harsh conditions. The large, non-slip footplate provides a stable base on soft ground, helping keep the trailer steady in mud, sand, or gravel.

Real-World Use Scenarios

• Heavy-duty trailers and RVs at campgrounds, job sites, or storage yards requiring solid support.
• On-site leveling where ground conditions vary from slick clay to gritty gravel.
• Towable setups that demand minimal space while maintaining stability when parked or serviced.

Why NBJINGYI Stands Out

• 8,000 lbs capacity with about 7,000 lbs lifting power for robust performance.
• 2.5" square tube design for enhanced side-load strength and stability.
• 360° swivel with a lock pin for flexible towing and secure storage.
• 28" lift range for quick, confident leveling on varied surfaces.
• Ergonomic sidewind crank and lubrication point for easy maintenance.
• Corrosion-resistant black E-coat finish and zinc plating with a large 4"x4" footplate.
