Frequently Asked Questions About Kenworth W990 Front Fenders & Acc.

Will these fenders fit my specific year model W990, and are there any compatibility issues I should know about?

Our W990 fenders are designed to fit all Kenworth W990 models from 2018 to present. However, some accessories may have slight variations depending on whether you have a standard or extended hood configuration. We recommend checking your VIN or calling our tech support at 1-888-875-7787 to confirm exact fitment, especially if your truck has aftermarket modifications or custom hood configurations.

What's the difference between fiberglass and steel fenders, and which material holds up better for long-haul applications?

Steel fenders offer superior durability and impact resistance, making them ideal for heavy-duty applications and harsh weather conditions. They typically last 15-20 years with proper maintenance. Fiberglass fenders are lighter (reducing overall vehicle weight by 40-60 lbs per fender), more affordable, and easier to repair for minor damage. However, they may crack under severe impact. Most long-haul operators prefer steel for longevity, while owner-operators focused on fuel efficiency often choose fiberglass.

How difficult is the installation process, and what tools or professional help will I need?

Fender installation typically takes 2-4 hours per side for experienced mechanics. You'll need basic hand tools, a drill with metal bits, and ideally a helper to hold the fender in place during mounting. The main challenges include proper alignment with existing bolt holes and ensuring adequate clearance for tire movement. While many drivers complete this as a DIY project, first-time installers often benefit from professional installation to avoid alignment issues that can cause premature tire wear.

What finish options are available, and do they come paint-ready or pre-painted?

Most fenders arrive in primer-ready bare metal or gel-coated fiberglass, requiring paint to match your truck. We offer chrome-plated steel fenders for a classic look, powder-coated black options for durability, and polished stainless steel for premium applications. Pre-painted options are limited, but our primer-ready surfaces accept all automotive paints. Many customers report best results using a professional paint shop to ensure proper color matching and finish durability.

Are mounting brackets and hardware included, or what additional parts will I need to complete the installation?

Fenders typically come with basic mounting brackets, but hardware packages vary by manufacturer. Most installations require additional items such as rubber fender liners ($45-85 per side), stainless steel bolt kits ($25-40), and mud flap hangers ($30-50). LED marker lights and wiring harnesses are sold separately. We recommend purchasing a complete installation kit to avoid multiple orders and ensure all components match your specific fender style.
