This fender is crafted from 12-gauge aluminum, offering rust resistance for marine environments and full coverage when paired with the correct tire diameter (14.88″ overall). It’s ideal for owners who prefer USA-made components and local support.
Why selected: The aluminum construction delivers strength and corrosion resistance, while the size range accommodates common boat trailer wheels. The product is manufactured in the USA, providing domestic support that can be advantageous for parts sourcing and warranty considerations in the long term.
Caution: Verify your tire’s overall diameter to ensure proper fit and prevent rubbing or insufficient coverage on tall fenders.
Tie Down Trailer Fenders Single Axle – 2 Fenders (13–16″)

Why selected: The 12-gauge aluminum design resists corrosion and holds up in saltwater and rain. The two-fender kit simplifies installation for trailers that require symmetrical coverage on both sides of the wheel.
Limitation: Ensure your mounting hardware and spacing align with the two-fender layout to avoid interference with trailer components or tire clearance.

Caution: This model emphasizes mounting versatility; ensure mounting points align with your trailer’s frame to avoid clearance issues.

Buying Guide
What material matters and why
Aluminum fenders resist rust and corrosion, making them ideal for marine environments. They are lighter than steel, which helps with trailer handling and gas mileage.
Which wheel size should you match?
Confirm the wheel size and overall tire diameter before purchasing. Most fenders in this guide cover 13″–16″ wheels with specific overall diameters to ensure proper coverage and clearance.
Single vs. double fender setups
Single-fender packages are compact and cost-effective for standard trailers. Dual fenders provide symmetrical coverage and may be preferred for wider tires or higher splash protection on rough surfaces.
USA-made quality and support
Products manufactured in the USA often come with domestic support, easier warranty handling, and nearer parts availability, beneficial for ongoing trailer maintenance.
Installation considerations
Check mounting hole patterns, frame compatibility, and potential interference with tires, hubs, or brake components. Some fenders are adaptable to various axle configurations, which can save time during upgrades.
Durability and finish
A tread-plate or diamond-plate finish can add durability and a rugged look, but may require more cleaning to retain a pristine appearance in saltwater conditions.
