TOWKING 1500 lb Trailer Swivel Caster Replacement 6" Spoked Wheel — Fits 2" Jack Tube, Powder-Coated Steel

The TOWKING 1500lbs 6" trailer jack swivel caster with spoked wheel is a heavy-duty replacement caster that transforms a 2" jack tube into a mobile, durable support for trailers, RVs, and motorcycles.

This caster is built to carry medium to large loads while resisting corrosion and reducing wobble. Designed to clamp securely to standard 2" diameter jack tubes, it delivers smoother maneuvering and dependable stability when moving or positioning trailers. The reinforced 6" spoked wheel and powder-coated steel body balance strength and long-term weather resistance so you can rely on the caster in outdoor environments.

How much weight can this swivel caster safely support?

The caster is rated for a 1,500 lbs static load capacity, suitable for many single-axle trailers, RV tongue loads, and motorcycles when used as intended. Load ratings assume proper installation on a compatible 2" jack tube and even weight distribution across the trailer’s support points. Avoid exceeding the rated capacity to maintain performance and safety.

• 1,500 lbs maximum load capacity
• Intended for medium to large trailer and RV tongue loads
• Designed for use on 2" diameter jack tubes

How does the caster attach and stay secure on the jack tube?

Installation uses an extra-tightening bolt and a safety pin design to clamp the assembly to the jack tube and minimize movement. The bolt allows you to tighten the clamp for a snug fit, while the pin ensures the caster stays locked in place during transport or repositioning. Together they reduce wobble and extend the life of the jack tube and wheel.

• Fits standard 2" diameter jack tubes for quick mounting
• Extra-tighten bolt secures the clamp and reduces wobble
• Safety pin prevents accidental disengagement during use

What materials and finishes improve durability and weather resistance?

The main structure is high-strength steel finished with a protective powder coat to fight rust and abrasion. The spoked 6" wheel is reinforced for load-bearing durability and reduced wear over time. Components meet SAE standards for consistent manufacturing quality and reliability in outdoor conditions.

• High-strength steel construction for structural integrity
• Powder-coated finish for corrosion and weather protection
• Reinforced 6" spoked wheel for longer service life
• SAE-compliant production for consistent quality

How easy is it to use the caster day-to-day?

The caster is made for fast on/off installation and straightforward operation: slip it onto the jack tube, tighten the bolt, and secure the safety pin. The swivel action lets you maneuver trailers into tight spaces without heavy lifting. Routine maintenance is minimal—periodic inspection and lubrication of moving parts keeps it rolling smoothly.

• Quick slide-on fit for 2" jack tubes
• Simple bolt tightening and pinned safety for secure mounting
• Swivel wheel eases trailer positioning and maneuvering
• Low-maintenance design with occasional lubrication recommended

It’s especially useful when you need better mobility and stability for stored or lightly used trailers, or when you want a reliable replacement for worn or damaged jack wheels. If you require a caster that balances load capacity, corrosion resistance, and straightforward installation, this model is a practical choice.
