Frequently Asked Questions About Kenworth T880 Front Fenders & Acc.

Will these fenders fit my specific year model T880, and are there differences between model years?

Kenworth T880 fenders are generally compatible across model years from 2013 to present, but there are important distinctions. The main differences occur between set-forward axle and set-back axle configurations, which require different fender lengths and mounting brackets. Additionally, fenders for daycab models may differ slightly from sleeper models in terms of mounting points. Always verify your truck's specific configuration (axle position, cab type, and year) before ordering to ensure proper fitment.

What's the difference between fiberglass and aluminum fenders, and which holds up better?

Fiberglass fenders are the most common OEM choice, offering good impact resistance, easier repairs, and lower initial cost. They typically weigh 15-20 pounds each and can be painted to match your truck. Aluminum fenders, while more expensive upfront, offer superior corrosion resistance and can last 2-3 times longer in harsh conditions. They're especially popular for trucks operating in northern states where road salt is common. Aluminum fenders also maintain better resale value but are more difficult to repair if damaged.

Do I need special brackets or hardware to install aftermarket fenders, or can I reuse my existing mounting hardware?

Most aftermarket T880 fenders are designed to use your existing OEM mounting brackets and hardware, but condition matters. If your current brackets are bent, rusted, or damaged, you'll need replacements. Standard installations require 6-8 mounting bolts per fender, rubber isolation mounts, and metal backing plates. Some wider aftermarket fenders or custom configurations may require bracket extensions or modified mounting points. We recommend ordering new stainless steel hardware kits if your bolts show any corrosion.

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

Installation typically takes 2-3 hours per fender for someone with basic mechanical skills. You'll need a socket set (typically 1/2" to 3/4" sizes), drill with metal bits for any new mounting holes, torque wrench, and ideally a helper to hold the fender in position during mounting. The most challenging part is usually removing old, corroded bolts and ensuring proper alignment. Professional installation runs $150-300 per fender at most shops. Critical tip: always test-fit before final mounting to check tire clearance at full steering lock.

What finishes are available, and can I paint fiberglass fenders myself?

Fiberglass fenders come in three main options: raw (unpainted), gel-coated white, or pre-primed gray. Raw and primed fenders are designed for custom painting and require proper prep work including sanding, filling any imperfections, and applying automotive primer before paint. Gel-coated white fenders can be used as-is or painted over. For DIY painting, use automotive-grade flexible paint designed for plastics to prevent cracking. Professional paint shops typically charge $200-400 per fender for color matching and painting. Aluminum fenders are available in polished or brushed finishes and generally aren't painted.
