Tell us what you need
Before you order fenders
A few things to check so the part fits the first time, or just tell us what you’ve got and the parts team will spec it with you.
- Single or tandem
- Single-axle fenders are short; tandem (teardrop/round) fenders span both wheels. Match your axle count.
- Check tire clearance
- Give us tire size and wheel width so the fender clears at full load.
- Pick the material
- Steel paints to match; aluminum and diamond-plate resist rust. We carry all three.
- Weld-on or bolt-on
- Tell us how yours attaches: weld-on or bolt-on with backs.

Fenders FAQ
- How do I measure for a replacement trailer fender?
- Three measurements: overall length front to back, width across the tire (make sure it clears your tire and any future upsizing), and height from the bottom edge to the top of the arch. Note whether it's a single-axle or tandem fender and the shape — round, flat-top (jeep style), or teardrop. With those, matching a replacement is straightforward.
- Should I choose steel or aluminum fenders?
- Steel is stronger, cheaper, and easy to weld — the default on work trailers — but it rusts where the coating gets chipped. Aluminum (usually treadplate) never rusts and looks sharp, but it dents more easily and costs more. If the fender doubles as a step, make sure whichever you choose is backed or braced for it.
- Are fenders bolt-on or weld-on?
- Both exist. Bolt-on fenders attach to brackets riveted or welded to the frame and swap out with hand tools. Weld-on fenders are welded directly to the frame or its brackets — stronger, but replacement means cutting and welding. Check how yours is attached before ordering; most of our stores can handle a weld-on swap if you'd rather not.
