TOWKING Trailer Jack Swivel Caster Dual 6" Wheels 2000 lb — Slip-On for 2" Tube, Powder-Coated

The TOWKING 2000lbs Dual 6" Trailer Jack Swivel Caster is a heavy-duty wheel assembly that slips onto 2" trailer jack tubes to give trailers smoother, more stable mobility and reliable load support.

Replace a worn jack wheel or upgrade your trailer’s maneuverability with this robust swivel caster from TOWKING. Built from high-strength steel with a protective powder coat and featuring twin 6" polypropylene wheels, this assembly is engineered for trailer owners who need corrosion resistance, easy installation, and a 2000 lb load rating. It’s SAE-compliant and designed to be a straightforward swap for most 2" diameter jack tubes.

How does this caster improve trailer movement?

The dual 6" PP wheels reduce rolling resistance and distribute weight more evenly than a single narrow wheel, making towing and positioning easier on hard and mixed surfaces. The swivel design lets you turn and align the trailer without straining the jack or using extra tools.

• Dual-wheel layout for smoother rolling and better balance.
• 6" polypropylene wheels resist flat spots and roll over small obstacles.
• 360° swivel action for simple directional changes at low speeds.

Will it fit my trailer jack and how simple is installation?

This unit slips onto standard 2" diameter jack tubes and secures with a safety pin design—no special tools required. The pin locks the assembly in place for secure operation while still allowing quick removal when needed.

• Designed for 2" jack tubes—measure your tube before ordering.
• Safety pin attachment for fast, tool-free mounting.
• Compact profile preserves clearance and ground contact.

What load and environmental protection does it offer?

Rated to support up to 2000 lbs, this caster handles medium to large trailers, including many boats and utility trailers. The powder-coated steel frame provides a rust-resistant barrier, extending service life in wet or coastal conditions.

• 2000 lb capacity suitable for heavier trailer applications.
• Powder-coated finish resists corrosion and chipping.
• SAE-compliant manufacturing for consistent quality standards.

How durable are the wheels and frame for long-term use?

The wheels are molded polypropylene, chosen for impact resistance and low-maintenance performance, while the supporting bracket is high-strength steel with a protective coating. This combination minimizes wear from road debris, salt, and general exposure so the caster remains functional season after season.

• PP wheels withstand wear and resist flat-spotting under load.
• High-strength steel bracket maintains structural integrity.
• Protective finish reduces rust and simplifies cleaning.

Who is this for? The TOWKING 2000lbs Dual 6" Trailer Jack Swivel Caster is aimed at trailer owners and service professionals who need a straightforward, durable wheel replacement for 2" jack tubes—especially those with medium to large boats, utility trailers, and equipment trailers. Choose this caster if you want easier trailer positioning, a higher load rating than economy wheels, and a corrosion-resistant finish for year-round use.
