XIANGZI Trailer Jack Wheel Replacement 6" x 2" Poly Caster for 2" Jack Tube, 1200 lb Capacity

The XIANGZI 6-inch trailer jack wheel replacement is a 6" x 2" caster that mounts to a 2" jack tube to add mobility and dependable tongue support up to 1,200 lb.

If you need to move, position, or couple a boat or utility trailer more easily, this replacement jack wheel swaps onto most 2" trailer jack tubes and gives a smooth, corrosion-resistant rolling surface. Built with zinc-plated steel hardware and a resilient poly tire, it’s a practical upgrade for older jacks or a direct spare part when the original wheel shows wear.

How does this wheel make trailer coupling and positioning easier?

The 6-inch diameter and 2-inch width provide a larger contact area than small caster wheels, reducing effort when maneuvering a loaded trailer by hand. The wheel rolls smoothly over docks, driveways, and grass, letting you line up the hitch with less strain.

• 6" x 2" poly wheel improves rolling over uneven surfaces
• Reduces lifting required when aligning coupler to hitch
• Included safety pin secures wheel for immediate use

Will this fit my trailer jack and how strong is it?

The mounting bracket is engineered to clamp onto standard 2" diameter trailer jack tubes, making it compatible with the majority of trailer jack assemblies. The assembly is rated for a tongue weight capacity up to 1,200 pounds, suitable for many small-to-medium boat and utility trailers.

• Fits trailer jacks with a 2" tube diameter
• 1200 lb tongue weight rating for dependable support
• Zinc-plated steel bracket resists corrosion in wet environments

How durable is the XIANGZI replacement wheel in marine environments?

The wheel and bracket are designed with longevity in mind: the bracket uses zinc plating to slow rust and the wheel uses a durable poly material that withstands abrasion and moisture. This combination keeps the replacement functional for longer periods where salt spray or freshwater exposure is common.

• Zinc-plated steel bracket for corrosion resistance
• Poly wheel resists wear, punctures, and water damage
• Solid construction minimizes maintenance and part failures

What comes in the package and is installation difficult?

The product ships with the wheel assembly and a safety pin for securing the wheel to the jack tube — no additional hardware is typically required. Installation is straightforward: slide the bracket onto the jack tube, align the hole, insert the pin, and you’re ready to roll.

• Complete wheel assembly pre-mounted to bracket
• Included safety pin for quick, secure installation
• No special tools usually required; simple slide-and-pin fit

Who is this for: The XIANGZI 6-inch trailer jack wheel replacement is a practical choice for boat owners, landscapers, DIYers, and anyone who operates small to mid-size trailers and needs easier manual maneuvering or a reliable jack wheel spare. It’s especially useful if your existing jack wheel is worn, corroded, or too small for the surfaces you typically encounter.
