Restore the smooth rolling performance of your boat or utility trailer with the Seachoice 8" Poly Black Spare Jack Wheel. Engineered as a direct, high-quality replacement wheel for trailer tongue jacks, this component is built to handle the heavy vertical loads of trailer maneuvering and tongue weights.

Constructed from a reinforced black polyolefin polymer, it delivers exceptional structural strength while maintaining smooth, effortless pivoting over concrete, asphalt, and packed boat ramp terrain.

Key Features

• Reinforced Polyolefin Build: Molded from heavy-duty, high-impact black polymer designed to resist flat-spotting, cracking, and weathering under demanding tongue weight loads.

• Marine-Grade Environment Proof: Unlike metal casters, the composite poly structure is completely rustproof and impervious to both fresh and saltwater exposure, making it ideal for boat trailers.

• Smooth-Rolling Performance: Features a wide, stable footprint that distributes weight evenly, allowing you to easily roll and position your trailer on tight driveways or at the marina.

• Direct OEM Fit: Built as an exact replacement wheel for Seachoice tongue jacks (such as the 1,500 lbs. series) and compatible with standard utility trailer jack wheel assemblies.
