ECOTRIC 2 Pcs Trailer Fenders With Steps
Best for: Single-axle trailers with 13″ wheels that benefit from built-in steps. These fenders are made of high-density polyethylene and include a fender skirt with an optional step pad. Drilling may be required for installation. Size: 29″(L) x 9″(W) x 12″(H); capacity 300 lb.

The 13″ wheel compatibility is clearly stated, making fitment straightforward for suitable trailers. Consider this option if you want a simple, utility-focused fender with extra practicality for routine checks and access.
Caution: Installation may require drilling. Verify wheel size and mounting points before purchase.
Trailer Fenders Single Axle (Steel) With Back Plates
Best for: Trailer owners who prioritize durability and a separate back plate for richer installation options. Although this product uses steel, its section on fender backers helps protect wheels from debris and supports longer-term endurance on rough roads.
Why this pick: The design features a separate back plate and built-in backer for debris protection, plus a robust steel construction that withstands demanding conditions. It’s better for buyers who want a sturdy, long-term solution and aren’t solely seeking plastic fenders.
Limitations: Heavier than plastic alternatives; installation may require more effort and hardware compatibility should be checked.

Best for: Small trailers with overall tire diameter around 5.19 inches. These fenders are UV-protected high-impact polyethylene, designed for compact wheels and tight spaces.
Why this pick: The compact dimensions (20.90″ L x 7.75″ W x 5.19″ H) deliver targeted protection without overwhelming limited fender wells. They’re ideal for small utility or cargo trailers where space is at a premium.
Caution: Designed specifically for small wheels; verify wheel and tire dimensions to avoid fitment issues.

Best for: Demco Kar Kaddy trailers that require a gray plastic right fender with bulb compatibility. The product emphasizes impact resistance and temperature-treated plastic for long service life.
Why this pick: The fender is designed to block splashed water and stones, protecting the upper portion of the vehicle while in motion. It’s a targeted fit for specific trailer models and can be a seamless replacement for worn components.
Caution: Verify compatibility with your exact Kar Kaddy model before purchasing, as fitment can vary by trailer generation.

Best for: Versatile kits that cover 14″ to 16″ wheels on single-axle trailers. Includes fenders and backs with a 32″ x 9″ x 15″ footprint, giving flexible mounting options for various trailers.
Why this pick: The set offers a practical solution for replacement or upgrade projects, with a robust design that supports easy welding surfaces and debris protection. The electrophoretic coating enhances rust resistance, contributing to longer life in harsh environments.
Limitations: The kit focuses on a larger wheel range; verify exact dimensions and mounting patterns to ensure proper alignment with your trailer.
Buying Guide: Key Considerations For Plastic Trailer Fenders
- Material: Plastic fenders are lightweight and corrosion-resistant, while some kits mix steel components. Choose plastic for rust resistance and ease of drilling, or steel for higher impact tolerance if your trailer faces heavy debris exposure.
- Wheel Size Compatibility: Confirm the wheel diameter your trailer uses (13″, 14″-16″ are common). Fenders must clear tires without rubbing at full suspension compression.
- Mounting and Backing: Look for fenders with back plates or built-in backers if you need extra protection against debris and easier installation.
- Protection Features: Built-in skirts, step pads, or bulb compatibility add functionality. Decide if you want extra steps or simple covers.
- Durability Factors: UV resistance, impact resistance, and temperature tolerance affect longevity in outdoor environments.
- Installation Ease: Some fenders require drilling or specialized hardware. Check your trailer’s mounting points and tools needed before purchasing.
- Fitment Notes: Some models are model-specific (e.g., Kar Kaddy compatibility). Confirm exact trailer model and year to ensure proper fit.
Frequently Asked Questions
- Do plastic fenders provide enough protection for rough roads? Yes, high-density polyethylene fenders offer good impact resistance and won’t rust, making them suitable for many road conditions.
- Can I use steel and plastic fenders together on the same trailer? It’s possible, but consistent mounting points and corrosion considerations should be evaluated to avoid imbalance or interference.
- Are fenders with backs easier to install? Generally yes, back plates or backs simplify mounting and provide additional protection against debris.
- What wheel size should I measure to pick the right fender? Measure the tire diameter and width when the tire is inflated to its normal operating size, then compare to the fender dimensions.
- Is drilling always required for plastic fenders? Not always; some models use pre-drilled mounting points while others require drilling for a secure fit.
- Do these fenders affect trailer clearance or loading height? Some fenders add a small clearance increase; confirm with your trailer’s wiring and wheel clearance to avoid interference.
