rockane Dual 6" Trailer Jack Swivel Caster Wheel Replacement — 2" Tube Fit with Rubber Chock, 2000 lb Capacity

The Rockane Dual 6" Trailer Jack Swivel Caster Wheel with rubber wheel chock is a direct-fit replacement wheel assembly that gives your trailer a smooth rolling jack and a secure chock to prevent unwanted movement.

If you need a reliable jack wheel that fits standard 2" diameter jack tubes, this Rockane assembly combines twin 6" poly wheels with a matching heavy-duty rubber chock. It’s built to resist corrosion and handle typical trailer tongue loads while making launching, docking, or relocating your trailer easier on soft ground or uneven surfaces. The package includes the swivel caster wheel assembly and a form-fitting rubber chock sized to cradle the wheel when parked.

How does this jack wheel improve moving and positioning my trailer?

The dual-wheel design distributes load and decreases ground pressure, so rolling across gravel, grass, or soft soil is steadier than a single narrow wheel. The swivel action gives better directional control for aligning the trailer tongue to a hitch or dolly without lifting the jack. For short moves around a campsite or driveway it reduces effort and prevents wheel sinkage.

• Dual 6" poly wheels for lower ground pressure and smoother roll.
• Swivel caster for easy maneuvering and directional control.
• Fits standard 2" diameter jack tubes — plug-and-play replacement.
• Poly construction resists wear and moisture for outdoor use.

What load can this assembly safely support and how is the chock used?

The dual-wheel jack assembly is rated to support up to 2,000 lbs of trailer tongue weight; when paired with the rubber wheel chock, the combined system can resist up to approximately 4,000 lbs in stabilization scenarios. The included chock is designed to cup the wheel and stop unintended rolling when the trailer is parked or during hookups.

• 2000 lb capacity for tongue weight on the caster wheel assembly.
• Wheel chock provides additional holding resistance up to 4000 lb scenarios.
• Chock dimensions match the 6" wheel profile for secure seating.
• Use chock on flat or slightly graded surfaces to block movement.

Will this fit my trailer jack and what are the key dimensions?

This Rockane jack wheel is made to fit standard 2" diameter jack tubes commonly found on trailers, campers, and boat hitches. The overall wheel assembly is sized for easy installation and the chock is proportioned to cradle the 6" wheel for positive engagement.

• Tube fit: designed for 2" diameter jack tubes (standard outer tube size).
• Wheel size: 6" diameter with overall assembly sizing approximately 6" x 6" x 9".
• Chock size: roughly 7" x 6.7" x 1.38", shaped to match the wheel profile.
• Installation uses the provided pin and common jack hardware for secure mounting.

The materials and build make it suitable for outdoor use without frequent replacement; the poly wheels resist abrasion and moisture while the solid rubber chock withstands compression and UV exposure.

Who is this for: Owners of trailers, campers, boat trailers, or utility trailers who need a sturdy, drop-in replacement jack wheel that improves maneuverability and adds a matched chock for parking security. It’s especially helpful for people who frequently move trailers on soft or uneven ground, as well as anyone wanting a corrosion-resistant alternative to stock caster wheels.
