Buying Guide: Key Purchase Considerations
- Material choice: Poly fenders are lighter and resistant to impact, while stainless steel offers superior corrosion resistance and longevity in harsh environments. Choose based on climate, road conditions, and maintenance preferences.
- Fitment: Look for universal vs. model-specific fit. Universal options provide flexibility across brands but may require minor adjustments for optimal alignment.
- Size and coverage: 24″ x 24″ is a common dimension offering balanced protection; 24″ x 34″ variants provide extended coverage on taller trucks or trailers. Consider spray patterns and wheel clearance when selecting size.
- Hardware and mounting: Kits that include brackets, bolts, posts, and washers save install time and reduce the risk of missing components. Check compatibility with existing mounting points on your truck.
- Protection goals: If you frequently drive in rocky or salty conditions, prioritize materials with abrasion resistance and easy cleaning. For fleets focused on longevity, stainless steel may be worth the extra weight and cost.
- Maintenance: Poly fenders may need occasional tightening and inspection for cracks or chips, while stainless options require minimal maintenance but heavier handling during installation.
