TOWKING Trailer Jack Swivel Caster — 6in Spoked Wheel, 1,500 lb Capacity, Powder-Coated Steel

The TOWKING 1500lbs 6" Trailer Jack Swivel Caster replacement is a heavy-duty, easy-to-install wheel assembly that converts a 2" jack tube into a smooth, swivel caster for improved trailer mobility.

Designed for trailers, RVs and medium-to-large towing gear, this replacement caster swaps onto standard 2" jack tubes to relieve strain when moving or positioning a loaded trailer. Built from powder-coated steel with a reinforced spoked 6" wheel and a bolt-tightening clamp, the assembly balances durability, corrosion resistance and straightforward installation.

How much weight can this caster safely support?

This unit is rated for a 1,500-pound static load capacity, making it suitable for many utility trailers, campers and small vehicles on dollies. The rating reflects the combined performance of the steel frame, spoked wheel and secure clamp design.

• 1,500 lbs maximum rated load for a single caster.
• Engineered for medium-to-large trailer applications and equipment moves.
• Reinforced spoked wheel reduces flex under load.

Will it fit my existing jack or post?

The caster is manufactured to fit standard 2" diameter jack tubes, so it installs quickly on most trailer jacks that match that size. An extra tighten bolt and safety pin lock the assembly to the tube and reduce wobble across a range of fits.

• Fits 2" diameter jack tubes—common on many trailers and RVs.
• Extra tighten bolt clamps the tube for a tighter fit across sizes.
• Safety pin design enables fast secure attachment and removal.

What materials and finishes protect it from weather?

The frame and wheel hardware use high-strength steel with a powder-coated surface to resist rust and visual wear from prolonged outdoor use. The spoked wheel is reinforced for longevity and to maintain performance in varied conditions.

• Powder-coated steel body for corrosion resistance and durability.
• Reinforced 6" spoked wheel for extended service life.
• Hardware designed for outdoor exposure and frequent handling.

How easy is installation and everyday use?

Installation is designed to be user-friendly: slide onto the 2" tube, align, insert the safety pin and tighten the bolt. The swivel caster action improves maneuverability, and periodic tightening keeps the assembly secure during repeated use.

• Quick slide-on fit for most 2" jack tubes—no special tools required for basic fitment.
• Safety pin secures the caster for safe transport and storage.
• Extra tighten bolt reduces wobble and adapts to slight tube-size variations.

Who this is for: The TOWKING 6" spoked-wheel caster is aimed at owners of travel trailers, utility trailers, motorcycle carriers and similar tow equipment who need a dependable, corrosion-resistant replacement wheel that eases movement and positioning. It suits DIYers and fleet operators wanting a straightforward upgrade to a standard 2" jack tube—where a robust 1,500 lbs capacity and long-lasting hardware are important.
