Buying Guide
What wheel size do I need to know before buying?
Fenders are sized to fit specific wheel diameters. Confirm the trailer wheel diameter (e.g., 8″, 12″, 13″) and overall tire diameter to ensure a proper fit. A mismatch can leave the tire exposed or prevent proper mounting.
Which material lasts longest in harsh environments?
HDPE (high-density polyethylene) and ABS resin are common. HDPE generally handles impact and weather well and resists cracking, while ABS resin can provide a clean look with robust protection. For heavy-use trailers, HDPE options are often favored.
Are built-in steps or skirts important?
Built-in steps can aid access to the trailer bed, while a skirt improves aerodynamics and debris protection. If you frequently load cargo, a fender with a step pad may be advantageous.
Should I choose a 2-pack or a 4-piece set?
Two fenders usually cover a single-axle setup on both sides. If you have dual axles, you’ll need multiple sets. A 2-pack is often a cost-effective choice for standard trailers requiring two fenders.
What about installation considerations?
Check mounting slots and hardware compatibility with your trailer frame. Some fenders include mounting points and step pads, which simplifies installation. Ensure the fender width and mounting hole spacing align with your trailer.
Summary of key buying considerations
- Wheel compatibility: confirm wheel diameter and total tire diameter.
- Material durability: HDPE vs. ABS for weather resistance and impact protection.
- Additional features: skirt, step pad, or built-in protection.
- Number of fenders: pair vs. single units depending on trailer setup.
- Installation fit: verify mounting hole spacing and clearance with tires.
