XIANGZI 6-Inch Trailer Jack Wheel Replacement

XIANGZI offers a compact 6-inch wheel with a 1200 lb capacity suitable for small to mid-sized trailer jacks. The wheel uses a polyamide construction known for durability and resistance to impact, making it a reliable upgrade for boat trailer jacks that encounter uneven surfaces. Its 5/8-inch bore and 2-inch hub length are compatible with common jack configurations, simplifying replacement. The wheel’s solid build helps reduce wobble and improve maneuverability during docking and launching.
Installation is straightforward, often requiring basic mounting hardware (not always included). This option stands out for users seeking a balance between lighter weight and strong support on a variety of terrains, including docks and ramp areas. It’s well-suited for frequent movers who need dependable performance without overly heavy wheels.
TOWKING 1200lbs 6inch Boat Trailer Jack Wheel

The TOWKING 6-inch wheel is engineered for 1200 lb load capacity and features a universal 5/8-inch bore, making it a broadly compatible replacement for many boat trailer jacks. The product includes essential mounting hardware, simplifying installation and ensuring a clean upgrade path. The wheel diameter and width are designed to provide steady rolling across varying surfaces, including concrete, gravel, and damp ramps. This makes it a practical choice for users who frequently reposition their trailer on boat ramps or storage lots.
As a dedicated jack wheel replacement, it emphasizes reliable performance with straightforward hardware—great for boaters who want a no-fuss upgrade that restores original maneuverability and stability to their tongue jacks.
iSaddle Dual Trailer Swirl Jack Caster Wheel Dock

iSaddle offers a dual-wheel caster solution designed to stabilize trailer jacks on soft or uneven ground. Constructed with premium nitrile rubber, it distributes weight more evenly and helps prevent sinking into mud, sand, or loose soil. The design also functions as a chock, limiting movement and maintaining a stationary tongue during parking or maintenance. The drainage feature reduces moisture buildup, which can extend wheel life in varied weather conditions.
This option is particularly valuable in wet or sandy environments where a single wheel can sink or slip. The dual-wheel approach provides improved balance, reducing strain on the jack and the trailer frame during docking and un-docking operations.
Better Boat Trailer Jack Wheel Replacement

Better Boat provides a robust 2000 lb capacity wheel set designed for heavy-duty use with boat trailers and other utility platforms. The kit includes a securing pin to slide over a 2″ diameter jack tube, enabling quick and secure maneuverability. Its 5.5″ wheel diameter on dual wheels offers solid roll across dock surfaces and ramp textures, reducing effort when repositioning a loaded trailer. The construction emphasizes marine-grade durability, with corrosion resistance suited to saltwater exposure and humid climates.
This option is ideal for boaters who regularly haul large watercraft or require a longer service life in harsh environments. The dual-wheel configuration also helps stabilize heavy loads during trolling and storage.
Lawei 2 Pack 6 Inch Boat Trailer Jack Wheels

Lawei’s two-pack offers practical, budget-conscious replacement wheels for 6-inch jacks. Each wheel is designed to handle up to 1200 lbs per wheel, making them a sensible option when outfitting a dual-axle setup or replacing worn wheels on single-axle trailers. The plastic construction is lightweight yet durable, with hardware included for quick installation. The wheels emphasize smooth operation and reduced noise, which benefits repeated trailer moves around marinas and storage lots.
Lawei wheels are suitable for a range of trailer setups beyond boating, including RVs and utility trailers. They provide a straightforward, cost-effective solution for maintaining reliable mobility on the water.
Buying Guide: Key Purchase Considerations
- Load capacity: Match the wheel to your trailer tongue jack’s maximum weight. Oversized wheels can add unnecessary effort, while undersized wheels risk wear or failure.
- Wheel diameter and width: Larger wheels roll over small obstacles more easily but may require more space. A 6-inch wheel is a common standard for many boat trailers.
- Bore size and mounting: Confirm bore diameter and hub length compatibility with your jack tube. Some products include mounting hardware, others require separate components.
- Material durability: Polyamide, nitrile rubber, and phenolic composites each offer different levels of impact resistance, wear resistance, and weather tolerance. Consider saltwater exposure, mud, and rain when choosing.
- Dual wheels vs. single: Dual-wheel assemblies provide more stability on soft surfaces or uneven ground, reducing the risk of sinking or tipping under load.
- Corrosion resistance: Marine-grade or weather-resistant finishes are preferable for prolonged outdoor exposure and frequent wet conditions.
- Installation effort: Some wheels arrive with hardware and pins for quick mounting, while others may require sourcing additional components.
- Compatibility: Check bore size, axle compatibility, and whether the wheel accommodates your current jack or requires an adapter.
- Maintenance: Look for wheels with drainage features and easy-clean surfaces to extend life in wet environments.
- Cost vs. durability: Higher capacity and dual-wheel designs typically cost more but offer longer service life and better stability for large boats.
When selecting a heavy-duty jockey wheel, consider the typical trailer weight, the environments you frequent (saltwater, freshwater, mud), and how often you move and store your trailer. Prioritize a model with robust materials, reliable load capacity, and straightforward installation to minimize maintenance while maximizing performance across boating seasons.
