Tie Down Trailer Fender Single Axle – Diamond Plated
Best for lightweight aluminum trailers, this single-axle fender is built from 12-gauge, 0.08 inch aluminum, offering strong corrosion resistance and durability in all weather conditions. The 33.74″ length and 9″ width provide ample coverage for 13–15″ tires. It’s designed to shield the trailer from debris, mud, and water, helping to keep tires and surfaces cleaner. The fender is manufactured in the USA, with local support for added peace of mind.
- Best for lightweight configurations where aluminum protection is preferred.
- Better for anglers, utility trailers, and light-duty haulers used in variable climates.
Limitations: Aluminum construction is lighter and may not be as resistant to heavy impact as steel in the toughest environments, so avoid use in high-abrasion applications where stone spray is extreme.
RecPro Tandem Axle Fender | Diamond Plate
Designed for tandem axle trailers, this 14-gauge steel fender combines rugged protection with an industrial diamond plate finish. The heavier steel construction provides robust protection against road debris and tire exposure, while the diamond plate texture adds durability and a bold look. It features bolt-on installation for straightforward mounting.
- Best for tandem trailers needing maximum durability and a rugged aesthetic.
- Better for heavy-duty utility or cargo trailers that encounter rough surfaces.
Caution: Steel fenders can be heavier and may require additional mounting hardware or reinforcement on lighter frames.
RecPro 10″ x 72″ x 20″ Aluminum Tandem Fender Diamond Plate
This aluminum tandem fender measures 10 by 72 by 20 inches, offering extended coverage for tandem trailers with 13–15 inch tires. Made in the USA, it uses high-quality aluminum (0.056″ thickness) for corrosion resistance and longevity. The 1″ radius lip enhances strength and protection against debris, making it a reliable option for frequent road use.
- Best for long tandem setups where extra length adds protection and coverage.
- Choose this if you prioritize a lighter, rust-resistant option with straightforward installation.
Limitation: Aluminum, while corrosion-resistant, can dent more easily than steel under harsh impact; ensure mounting is tight to reduce movement.
Boat Trailer Diamond Plate Fender Covers Protect Your Fender for Stepping Wow

- Best for boat trailers needing aesthetic enhancement and added surface protection.
- Better for users who want a quick visual upgrade without heavy modification.
Limitation: Covers are aesthetic accessories and may not replace full fender protection in very rough terrain.

The dimensions are tall and wide (10-1/4″ x 72-7/8″ x 13″), making them suitable for rugged use on tough job trailers. The steel construction ensures long-lasting protection against debris and impacts in demanding environments.
- Best for heavy-duty applications like landscaping, equipment carriers, or car haulers.

- Weather exposure: Marine or wet environments benefit from corrosion-resistant metals and protective finishes.
- Installation: Bolt-on designs are easier to install; verify compatibility with existing mounting points.
