1. Buyers Products 2602019 Black Plastic Fender: Best Overall
In our evaluation, the Buyers Products 2602019 stood out due to its .150 inch thick polyethylene construction, which exceeds the standard thickness of many competitors. We compared its impact resistance against industry specs and found it highly effective against rocks and road debris. Owner feedback confirms this model maintains its shape and integrity even after years of exposure to harsh elements.
However, we noted that some users reported alignment issues during installation on non-standard trailer frames. You should skip this model if you require a fender with pre-drilled holes that perfectly match a custom or unusual frame pattern without modification.
- Resistant to cracking and chipping
- Fits most standard tandem axle trailers
- Pre-drilled mounting holes for easy alignment
Pros: Extremely durable material thickness; Excellent UV resistance prevents fading
Cons: Mounting hardware not included; Holes may not align with all custom frames
2. Dee Zee DZ76B Plastic Fender: Best Premium
We researched the Dee Zee DZ76B and found its extruded black poly construction offers a rigid yet flexible barrier against tire spray. Our comparison indicates it provides excellent protection for the trailer sides and the tow vehicle. The material is impervious to rust, making it a top choice for boat trailers used in saltwater environments based on corrosion resistance standards.
A limitation we observed is that the stiffness of the material, while durable, makes installation more challenging on uneven surfaces compared to more flexible models. Buyers with heavily modified or uneven trailer frames might find the mounting process difficult without additional brackets.
- Superior impact resistance
- Slim black finish
- Maintenance-free material
Pros: Strong brand reputation for quality; Sturdy build quality resists warping
Cons: Higher cost than average options; Bulky packaging can lead to shipping damage
3. MaxxHaul 70208 Black Plastic Trailer Fender: Best Value
Based on our research of value-oriented options, the MaxxHaul 70208 delivers reliable protection without a high price tag. We compared its dimensions to standard tandem axle requirements and found it offers a wide profile that effectively blocks water and mud. The pre-drilled holes simplify the mounting process for most standard setups.
Our evaluation of owner feedback reveals that the plastic material can flex significantly if the trailer is heavily loaded or tires are large. We recommend skipping this fender if you frequently haul heavy equipment where the tires might make contact with the fender during suspension compression.
- Wide profile for maximum coverage
- Easy installation with pre-drilled holes
- Rust-proof construction
Pros: Affordable price point; Good coverage area for debris
Cons: Plastic can flex under heavy tire load; Finish may fade over long periods
4. Reese Towpower 74338 Single Axle/Tandem Fender: Reliable Choice
We evaluated the Reese Towpower 74338 and found it to be a solid, utilitarian option for standard utility trailers. Its thermoplastic construction is lightweight, making it easy to maneuver during installation. The fit is compatible with a range of wheel sizes from 8 to 12 inches, providing versatility for different tandem axle configurations.
However, our analysis of long-term reviews indicates that the material is thinner than our top picks and may fade after prolonged sun exposure. This model is best suited for light duty use or covered storage, so heavy haulers should look for a more durable alternative.
- Fits 8 to 12 inch wheels
- Lightweight design
- Standard mounting pattern
Pros: Easy to handle during installation; Widely available and recognized brand
Cons: Prone to fading over time; Thinner material than premium picks
5. Camco 42691 Modular Fender: Best Modular
The Camco 42691 features a modular design that we found useful for custom trailer applications where standard fenders will not fit. Our research into blow-molded polyethylene shows it provides decent impact resistance. The textured surface is a practical feature, as it helps mask surface scratches that occur during normal use.
Based on owner feedback, the necessity to purchase mounting brackets separately can be frustrating and increases the overall setup complexity. You should avoid this model if you want a straightforward, bolt-on solution out of the box.
- Modular design for custom fit
- Textured surface for durability
- Lightweight and easy to clean
Pros: Customizable fit for unique trailers; Textured finish hides scratches well
Cons: Mounting brackets often sold separately; Assembly can be time consuming
6. MotoAlliance ImpactATV Trailer Fender: Best Compact
We compared the MotoAlliance ImpactATV fender and identified it as a strong candidate for smaller tandem axle setups or tight clearances. It is constructed from 1/4 inch thick polyethylene, which is surprisingly strong for its compact size. The material is UV stable, ensuring it does not become brittle quickly in the sun.
A significant drawback noted in our evaluation is the narrow profile, which may fail to fully cover wider tires common on larger tandem axle trailers. This results in more road spray reaching the side of the trailer, so buyers with wider tire stances should skip this option.
- Compact size for tight clearances
- Heavy duty for small trailers
- UV stable material
Pros: Very tough material for its size; Good for smaller utility trailers
Cons: Narrow profile may not cover larger tires fully; Limited aesthetic appeal
7. Rugged Ridge 13510.01 Jeep/Towing Fender: Honorable Mention
Our research included steel options like the Rugged Ridge 13510.01, which offers a classic aesthetic and high rigidity. The powder coating provides a layer of protection against the elements. For users who prefer the look and feel of metal over plastic, this fender provides a distinct alternative.
However, we found that once the powder coating is chipped by road debris, the underlying steel is prone to rapid rust formation. Based on owner feedback regarding corrosion, we cannot recommend this for use in salty or wet climates unless you are diligent with maintenance and touch-up paint.
- Powder coated finish
- Classic rigid look
- Highly rigid structure
Pros: Rigid feel provides a classic look; Strong resistance to impact
Cons: Susceptible to rust if coating chips; Heavier than plastic options
Frequently Asked Questions
What material is best for trailer fenders?
Based on our research, polyethylene is generally the best material for most applications because it is rust-proof, lightweight, and resists cracking. Steel fenders offer a classic look but require rigorous maintenance to prevent rust, especially in snowy or coastal regions where salt is used on roads.
How do I measure for tandem axle fenders?
We compared sizing guides and recommend measuring the width of your tire and adding a few inches on each side for coverage. You must also measure the distance from the trailer frame to ensure the fender is wide enough to cover the tire without rubbing against the trailer body during suspension movement.
Do these fenders come with mounting hardware?
In our evaluation, we found that most fenders do not include comprehensive mounting hardware kits. While the fenders themselves are pre-drilled, you typically need to purchase bolts, nuts, and washers separately that are specific to your trailer frame thickness and material.
Are plastic fenders durable enough for highway speeds?
Our analysis of high-quality polyethylene fenders confirms they are designed to withstand highway speeds and wind resistance. However, thinner economy models may flex or chatter at high speeds. We recommend choosing models with adequate thickness, such as .150 inches, for highway stability.
Can I paint these plastic fenders to match my trailer?
Owner feedback indicates that plastic fenders can be painted, but it requires specific plastic-compatible paint and proper surface preparation. We found that simply spraying standard paint often leads to peeling. For the best results, using a plastic adhesion promoter is essential based on automotive refinishing standards.
Our Verdict
Our research identifies the Buyers Products 2602019 as the top pick due to its superior material thickness and durability. For those needing a premium rust-proof option, the Dee Zee DZ76B is a strong runner up.
