Frequently Asked Questions About Kenworth W900B/W900L Front Fenders & Acc.
What's the difference between aftermarket and OEM fenders, and which should I choose?
Aftermarket fenders typically use 16-gauge steel (versus OEM's 18-gauge) and often feature reinforced mounting brackets. While OEM fenders guarantee exact fit, quality aftermarket options from brands like Jones Performance and Hogebuilt offer comparable or better durability at 30-40% less cost. For daily drivers and work trucks, aftermarket fenders provide excellent value. Choose OEM if you need exact factory specifications for show trucks or warranty requirements.
Will these fenders fit both W900B and W900L models, and what years are compatible?
Most front fenders are interchangeable between W900B (hood-mounted mirrors) and W900L (door-mounted mirrors) models from 1987-present. However, pre-1987 models have different mounting hole patterns. Always verify your specific year and check for variations in headlight cutouts - some 2007+ models have different configurations. Extended hood models may require different fender brackets or spacing adjustments.
How difficult is the installation, and what tools do I need?
Installation typically takes 3-4 hours per side for experienced mechanics. You'll need basic hand tools, a drill with metal bits, and ideally a helper for alignment. Common challenges include aligning mounting holes (some drilling may be required), adjusting hood-to-fender gaps, and ensuring proper headlight bucket fitment. Many customers recommend test-fitting everything before final installation and having shims ready for fine adjustments.
Do painted fenders match factory colors, and how durable is the finish?
Pre-painted fenders use automotive-grade paint but may have slight color variations from your existing paint due to fade and weathering. Most suppliers offer paint codes matching, but perfect matches are rare on trucks over 5 years old. For best results, order primed fenders and have them painted locally. Powder-coated options provide superior chip resistance for work trucks but limit color choices to basic black or white.
What accessories should I order with my fenders to complete the installation?
Essential accessories include: mounting brackets (if not included), rubber fender-to-hood seals, stainless steel bolt kits, and mud flap hangers. Consider adding fender guards for extra protection and LED marker lights if upgrading from older styles. Budget an extra $150-250 for these components. Many customers also replace headlight buckets and bezels while the fender is off for a complete refresh.
