HECASA Tandem Axle Diamond Plate Fenders

The HECASA fenders are designed for tandem axle trailers and fit most 13″-15″ tires. Constructed from Q235 steel with a diamond plate surface, these 10-1/4″ wide by 72-7/8″ long and 13″ tall fenders emphasize durability for heavy-duty use. They’re suited for equipment‑heavy loads on landscaping, car hauler, or utility trailers, delivering long-lasting protection from debris and brush while guarding tires from contact with protruding gear. Installation commonly involves welding to the frame or mounting to brackets, depending on your trailer’s configuration.
ECOTRIC Tandem Fender Teardrop 2 Pack

This pair features a teardrop center design and is intended for tandem axle trailers with 13″-15″ wheels. The tear‑drop profile helps shape airflow around the wheels while providing protective coverage from road debris. Made from cold rolled steel, these fenders are typically welded or mounted with hardware to the trailer frame. They’re well suited for enclosed trailers, utility setups, and landscape equipment carriers where a clean, rounded look complements rugged functionality.
ECOTRIC Round Fenders With Backs (2 Pack)

ECOTRIC’s round fenders with backs are designed for 14″-16″ wheels and come in a 2‑pack. The steel construction prioritizes durability, with a design that accommodates straightforward mounting to the trailer frame or bracket. The fenders are suited for car haulers, cargo trailers, and landscape trailers where both protection and a classic round silhouette matter. They also offer decorative potential while keeping the wheels shielded from debris and the trailer’s exposed body safe from minor scrapes.
D2E Trailers Tandem Fender with Backplate

The D2E tandem fender features a treadplate backplate and a 10x72x19 size with a 14 gauge backplate. It’s designed for tandem axle setups and is commonly welded or bolted to the trailer frame. The rugged finish helps guard against road debris while the backplate provides additional structural support. Shipping notes indicate variations in delivery timing and handling, which is typical for oversize trailer parts, and light surface rust can occur during transit due to humidity in certain regions.
JY PERFORMANCE Round Trailer Fenders With Backs

JY PERFORMANCE offers single axle, round fenders designed for 14″-16″ wheels, including a built-in backer. The construction uses premium steel for long-term durability, with the backer providing additional debris protection. This setup is ideal for single axle trailers that need a secure, clean look without compromising wheel coverage. Proper installation typically involves welding or bracket mounting to the trailer frame or existing supports.
ECOTRIC Square Trailer Fenders (2 Pack)

These square fenders are designed for 14″-16″ wheels and come in a two‑pack suitable for replacing damaged units on multiple trailers. They are constructed from 16 gauge steel, offering a robust balance of strength and weight. The 32±0.5″L x 9±0.5″W x 13±0.5″H dimensions, along with a 90‑degree edge on one side, provide a clean, protective shield around the wheel and partial body. They mount firmly to frames or brackets, supporting a straightforward upgrade path.
ECOTRIC Tandem Axle Diamond Fenders (2 Pack)

This tandem axle option uses 14‑gauge steel and a diamond tread plate surface, delivering rugged protection for tires and debris on tandem trailers. The fenders measure 10-1/4″ wide by 72-7/8″ long and 13″ tall, fitting most 13″-15″ tires. The dual‑fender design provides symmetrical coverage with welding or bracket mounting as common installation methods. It suits cargo, utility, and landscape trailers that demand a heavy‑duty shield against road hazards.
Tie Down Diamond Plated Aluminum Fenders

Tie Down’s aluminum fenders are diamond plated, built for 13″-16″ wheels, and designed for single axle applications. The dimensions are 34″ long, 10″ wide, and 18″ tall, offering substantial wheel protection with a lightweight, corrosion-resistant profile. Aluminum construction helps minimize weight impact on trailer handling while maintaining strong debris shielding across various weather conditions and road surfaces.
Buying Guide: Key Purchase Considerations
- Trailer compatibility: Verify tire size (13″-15″ or 14″-16″), axle configuration (single vs tandem), and mounting style (weld-on vs bracket-mounted) to ensure proper fit.
- Material and finish: Steel fenders deliver rugged durability; aluminum options reduce weight and resist corrosion. Diamond plate surfaces provide added grip and style but may add weight.
- Protection level: Consider rounded teardrop or square profiles based on debris exposure, trailer type, and whether fenders must shield the wheel and frame equally.
- Backer and mounting hardware: Some models include backers or require separate hardware; ensure you have compatible brackets or brackets for a secure installation.
- Installation considerations: Welding vs bolting affects trailer frame compatibility and required tools. For DIY installs, choose designs with clear mounting points and accessible hardware.
- Delivery and handling: Larger fenders may ship separately or require extra handling, especially for tandem axle configurations. Plan installation timing accordingly.
- Longevity and warranty: Look for fenders with corrosion resistance, robust gauge steel or quality aluminum, and manufacturer warranties where available.
When selecting fenders, balance durability, weight, and ease of installation with expected usage. For trailers used in landscaping, construction, or frequent loading/unloading, steel with a diamond plate finish often provides the best protection and durability. For lighter trailers or corrosion-sensitive environments, aluminum diamond plated fenders offer a lighter option with strong resistance to rust. Always confirm compatibility with your trailer’s tires, axles, and mounting points before purchase to ensure a secure, long‑lasting fit.
