ECOTRIC Tandem Trailer Fender: Double Axle 13-15 Inch
The ECOTRIC fender is a round, tear-drop center design built for tandem-axle trailers with 13″ to 15″ tires. It provides wheel protection from road debris and helps prevent tire damage on enclosed trailers. Best for buyers who want straightforward weld-on or hardware-mounted installation (hardware not included) and a rugged cold-rolled steel construction. This option suits DIY mechanics aiming to reinforce the trailer body where fenders attach.
Best for: trailer owners who prioritize robust, welded-on protection for 13–15 inch tires on tandem axles, especially enclosed trailers. Better for: those needing a durable, basic fender that withstands road debris. Avoid: if you require a lightweight aluminum variant or pre-install hardware included.

These tandem axle fenders are designed for 13″ to 15″ tires, with a 66″ length, 9.1″ width, and 20″ height. They use heavy-duty 14-gauge steel and feature welded surfaces on both sides for added protection. The welded design provides a sturdier attachment point, making them suitable for frequent trailer use and harsher road conditions.
Best for: users seeking a long, protective shield across the wheel wells with weldable surfaces for secure fastening. Better for: those who want durable steel construction with pre-drilled holes for easier mounting.

Buying Guide: Key Considerations For Double Axle Pontoon Trailers
What to prioritize when outfitting a double-axle pontoon trailer:
- Tire compatibility: Verify that fenders fit 13″–15″ tires if your trailer uses that size. Size mismatches can reduce clearance and protection.
- Material selection: Steel offers maximum durability but is heavier; aluminum reduces weight and resists corrosion but may require different mounting hardware.
- Mounting method: Weld-on versus hardware-mounted fenders. Welding provides permanent strength but needs skilled labor; hardware mounting offers flexibility but may require brackets and hardware not included.
- Axle and hub compatibility: When replacing axles or bearings, match hubface length, spring center, and bolt patterns to avoid alignment issues and uneven tire wear.
- Protection level: Choose fenders with reinforced edges or tear-drop centers for extra protection against road debris and tire impact.
- Maintenance and upgrades: Bearings kits and seals should align with spindle size (#84 spindles in these products). Plan for spare parts to simplify future repairs.
Frequently Asked Questions
- What is a hubface measurement?
It’s the distance between the two wheel hubs on either side of the axle, critical for matching axles and fenders. - Do I need aluminum or steel for trailer fenders?
Aluminum is lighter and corrosion-resistant, good for marine environments; steel is more durable and affordable but heavier and prone to rust without coating. - Can fenders be welded or do they require brackets?
Some fenders are weldable on both sides, others require brackets and hardware. Check product details for mounting options. - What should I consider when replacing an axle kit?
Confirm the hub size, spring center, hubface length, bolt pattern, and trailer weight to ensure a proper fit. - Is a complete axle kit better than individual parts?
For extensive repairs or upgrades, a complete kit simplifies installation and compatibility checks. - How do I know if a fender is suitable for my tandem trailer?
Verify tire size compatibility, mounting method, and overall dimensions align with your trailer’s wheel wells and frame.
