TOWKING Trailer Jack Swivel Caster 1500 lb 6" Spoked Wheel — Galvanized, Fits 2" Tube

The TOWKING 1500lbs 6" Trailer Jack Swivel Caster is a heavy-duty replacement wheel assembly that converts 2" jack tubes into a smooth, swiveling caster for easier maneuvering of trailers and RVs.

When you need to move, position or store a trailer, boat, or RV by hand, the right replacement caster makes the difference between a frustrating struggle and simple, controlled movement. This TOWKING caster is engineered to mount on standard 2" jack tubes, deliver up to 1,500 pounds of rated load capacity, and stand up to outdoor conditions with a galvanized, corrosion-resistant finish. It combines a reinforced 6" spoked wheel with an extra-tighten bolt and a safety pin for quick installation and a secure fit.

How does this caster improve trailer maneuverability?

The swivel caster adds a rolling pivot to your trailer jack so you can steer the trailer by hand rather than lift it. The 6" diameter spoked wheel reduces rolling resistance and handles uneven surfaces better than small solid wheels.

• 6" x 2" spoked wheel for smoother rolling over gravel and pavement.
• Swivel design enables 360° rotation for easy steering and alignment.
• Reinforced materials resist deformation under load for consistent movement.

Will this fit my trailer’s jack tube?

This caster is designed specifically for 2" diameter jack tubes and includes features to accommodate slight size variations. The assembly fastens securely using an extra-tighten bolt and safety pin to prevent wobble or slippage.

• Fits standard 2" diameter jack tubes commonly used on trailers and RVs.
• Extra-tighten bolt clamps the tube firmly to minimize play.
• Safety pin locks the assembly in place for quick, dependable installation.

How durable and weather-resistant is the TOWKING caster?

Built from high-strength steel with a galvanised finish, the TOWKING caster resists rust and corrosion in outdoor storage and marine environments. The spoked wheel structure reduces weight while maintaining strength for long-term use.

• Galvanised steel surface offers protection against moisture and rust.
• Spoked wheel design balances durability and reduced rolling weight.
• SAE-compliant manufacturing standards for reliable quality control.

What load can this caster safely carry and where is it best used?

Rated for 1,500 lbs, this caster suits medium to large trailers, small campers, utility trailers, and motorcycles on a dolly or jack assembly. It’s intended for occasional towing prep, storage repositioning, and short-distance hand maneuvering rather than constant on-road loads.

• 1,500 lbs rated capacity for medium and larger trailer applications.
• Ideal for RV tongue jacks, boat trailers, motorcycle transport stands, and utility trailers.
• Not a replacement for axle or road-bearing wheels — for positioning and storage use.

Who is this for: The TOWKING 1500lbs 6" Trailer Jack Swivel Caster is aimed at trailer owners, RV enthusiasts, boaters, and DIY mechanics who want an easy-to-install, heavy-duty solution to move and position trailers by hand. If you have a standard 2" jack tube and need a corrosion-resistant, SAE-compliant caster with a high load rating and a robust spoked wheel, this product offers a dependable, long-lasting upgrade that simplifies trailer handling and parking.
