TOWKING 2000 lb Trailer Jack Swivel Caster 8" Spoked Wheel for 2" Jack Tubes — Bolt‑On, Corrosion‑Resistant

The TOWKING 2000lbs 8" Trailer Jack Swivel Caster Replacement is a heavy-duty, bolt-on spoked wheel assembly that converts 2" trailer jack tubes into a smooth-swiveling caster for easier moving and stable support.

Whether you're repositioning a boat, camper, or utility trailer, the TOWKING swivel caster is designed to make handling easier while meeting SAE quality benchmarks. Built to fit 2" diameter jack tubes and rated for 2,000 pounds, this caster combines a large 8x2" spoked wheel with a secure tightening bolt and corrosion-resistant finish. The assembly is intended for straightforward installation using the included safety-pin design and offers a reliable replacement option when your original jack wheel is worn or missing.

How do I know this jack swivel will fit my trailer?

Fit depends on the distance from the lowest operating jack position to the ground or hitch point. Measure the gap when the jack is fully down; if that gap exceeds 11.3 inches the unit is compatible. The caster clamps to standard 2" diameter jack tubes and includes an extra tighten bolt to accommodate small variations in tube size and reduce wobble.

• Required gap: greater than 11.3" in lowest operating position
• Tube diameter compatibility: 2" jack tubes
• Adjustability: extra tighten bolt for tighter clamping
• Installation aid: safety pin secures the assembly quickly

How much weight can the TOWKING swivel caster support and where is it best used?

This replacement caster is rated up to 2,000 pounds, making it suitable for medium to large trailers including many boat trailers, campers, and utility trailers. Ratings reflect static support under typical conditions; always account for dynamic loads and uneven terrain when moving trailers. Use the caster for ground maneuvering, short-distance repositioning, and parking alignment rather than long-distance towing.

• Load capacity: 2,000 lbs
• Ideal applications: boat trailers, campers, utility trailers
• Best for: repositioning, parking, and storage movements
• Not intended for: sustained highway towing while attached to the jack

What features make installation fast and secure?

The TOWKING design emphasizes quick attachment and a solid hold. A safety pin design locks the caster to the jack tube and an extra tighten bolt eliminates play between tube and clamp. Installation requires minimal tools and a few minutes, returning immediate improved mobility and reduced wobble.

• Attachment method: safety pin for quick lock-in
• Securement: extra tighten bolt reduces play
• Compatibility: clamps onto 2" jack tubes without welding
• Tools needed: common hand tools only, basic installation steps

How does the caster resist weather and wear over time?

The assembly is made from high-strength steel with a powder-coated finish to resist rust, chipping, and corrosion from road salt and marine environments. The spoked 8x2" wheel is engineered for durability and smoother rolling across gravel, pavement, and launch ramps. SAE-compliant manufacturing standards help ensure consistent quality and longevity under normal trailer-use conditions.

• Material: high-strength steel construction
• Finish: powder-coated surface for corrosion resistance
• Wheel design: 8x2" spoked wheel for long-lasting mobility
• Standards: manufactured to SAE guidelines

It's a practical choice for boat owners, RV and camper users, landscapers, and anyone who regularly maneuvers medium to large trailers in storage yards, driveways, or marinas. If you require a corrosion-resistant, higher-capacity caster that reduces wobble and improves trailer handling, this product is a suitable replacement option.
