RecPro 9″ x 72″ Aluminum Tandem Fender | Diamond Plate
Material and build: Also built in America using .056” 3003 aluminum, this fender provides robust protection with a diamond plate finish offering extra grip and a rugged aesthetic. It fits tandem axles and shares the same simple mounting geometry as the smooth version.
Who it’s best for and why: Choose this if you want a tougher, more industrial look that hides scuffs and wear better than a smooth surface.
Limitation: Diamond plate texture can be harder to clean than smooth surfaces; plan for periodic maintenance to keep the finish looking new.

Material and build: This 2-pack uses .057 aluminum tread plate and is designed for tandem axles. The teardrop design is paired with a 1″ lip at the back to aid mounting, making it a solid option for owners seeking a rugged look with practical mounting features.
Who it’s best for and why: Best for buyers who want enhanced side protection and a bold tread plate appearance. The two-pack is convenient for full axle coverage on dual-fender trailers.

Material and build: A 2-piece set of tandem tread plate fenders, each measuring 72″ L x 20″ H x 10″ W, made from .057 aluminum tread plate. These are designed for side-mount on enclosed cargo trailers and provide strong protection for dual axles.
Who it’s best for and why: Best for buyers needing extra width and protection across both wheels on a tandem axle setup, especially for enclosed trailers where wheel exposure is a concern.
Limitation: Slightly taller than some 9″ x 20″ options; verify wheel clearance and mounting space before purchase.
Buying Guide: Key Considerations For 9 x 72 Tandem Trailer Fenders
- Material choice: Aluminum fenders are lightweight and corrosion resistant, ideal for long-term exposure to the elements. Steel options can be cheaper but heavier and prone to rust without coating.
- Finish and texture: Smooth finishes are easy to clean but may show wear; tread plate offers rugged protection but adds weight and requires more cleaning attention.
- Mounting style: Look for a 1″ lip or back lip design to simplify mounting on tandem axles. Ensure the mounting holes align with your trailer’s existing brackets.
- Size and fit: Confirm the exact dimensions (72″ L x 20″ H x 9″ W) and ensure wheel size compatibility, especially for 14–15″ wheels mentioned in some products.
- Quantity: If covering both wheels on a tandem axle, 2-pack sets save time and ensure uniform appearance.
- Durability vs. weight: Aluminum fenders offer a good balance of strength and weight; tread plate adds protection but increases weight and cost.
- Installation practicality: Some options are designed for weld-on installation or simple mounting with existing hardware. Choose based on your trailer’s construction and shop capabilities.
