Buying Guide
What should you consider when choosing trailer fenders?
- Wheel compatibility: Confirm 13″–15″ tire compatibility and the axle configuration (single vs. tandem).
- Material and finish: Steel fenders (diamond plate or standard) offer durability; consider rust protection like electrophoretic finishes.
- Welding vs. bolt-on: Weldable sides provide secure mounting but require welding or brackets; bolt-on options offer easier installation.
- Dimensions: Match length and width to your trailer frame and wheel coverage needs. Measure existing fender mounting points.
- Weight considerations: Heavier steel fenders provide durability but may affect trailer tongue weight and handling.
How to install?
- Inspect mounting brackets and frame for rust and damage before installation.
- Use pre-drilled holes where provided; align with trailer frame rails to avoid tire interference.
- Weld or bolt securely; verify clearance around tires during full suspension travel.
Frequently Asked Questions
- Are 13-15 inch tire fenders universal for tandem axles?
Most are designed to fit 13″–15″ tires, but always verify mounting hole patterns and frame clearance for your specific trailer model.
- What is the advantage of a weldable fender design?
Weldable sides offer a solid, long-lasting attachment and better debris protection when bracket mounting is used on rugged trailers.
- Do these fenders require special coatings after welding?
Yes, applying rust-preventive paint or coatings after welding helps extend life in harsh environments.
- Can I mix different brands on the same trailer?
Mixing brands is possible if sizes and mounting patterns match; otherwise, alignment and fit may be compromised.
- What is the typical installation time for a rear tandem fender replacement?
Simple bolt-on installations may take under an hour per side; welded installations may require more time and tools.
