Kenworth W900B/W900L Exterior Parts

Frequently Asked Questions About Kenworth W900B/W900L Exterior Parts

What years and models are compatible with W900B/W900L exterior parts?

W900B parts typically fit models from 1987-2010, while W900L parts are designed for long-hood models from 1989 to present. However, compatibility can vary by specific part. For bumpers, grilles, and fenders, the main difference is the hood length - W900B has a 119" BBC (Bumper to Back of Cab) while W900L has a 130" BBC. Always verify your truck's exact year and BBC measurement before ordering, as some parts like visors and mirrors are interchangeable while others are model-specific.

What material options are available and which hold up best?

Most aftermarket bumpers come in 304 stainless steel, chrome-plated steel, or aluminum. Stainless steel offers the best long-term durability and corrosion resistance, especially in harsh weather conditions. Chrome-plated steel provides a mirror finish but requires more maintenance to prevent rust. Aluminum is lightweight and won't rust but may show wear faster. For fenders and other body parts, fiberglass is common and offers good durability when properly maintained. Consider your climate and maintenance preferences when choosing materials.

Can I install these parts myself or do I need professional help?

Many exterior parts like bug shields, visors, and mirror brackets can be installed with basic tools and mechanical knowledge. However, bumpers typically require two people and proper lifting equipment due to weight (steel bumpers can weigh 100-200 lbs). Fender installation often requires drilling and precise alignment. Some parts may come with mounting hardware, but you may need additional tools like drill bits, wrenches, and alignment tools. Professional installation is recommended for major components if you lack experience or proper equipment.

What finish options work best for different driving conditions?

Mirror-polished chrome provides the showroom look but requires frequent polishing and isn't ideal for winter driving due to salt damage. Brushed or satin finishes hide minor scratches better and require less maintenance. Powder-coated parts offer excellent durability for work trucks but limited shine. For harsh environments, consider stainless steel with a brushed finish or powder-coated aluminum. Texas and California drivers often prefer high-polish chrome, while northern drivers typically choose more durable finishes.

Will aftermarket parts affect my warranty or resale value?

Quality aftermarket exterior parts from reputable manufacturers typically don't void warranties as they don't affect mechanical systems. However, improper installation can cause issues. For resale value, well-maintained chrome and stainless parts often increase appeal and value, especially OEM-style replacements. Custom or heavily modified exteriors may limit your buyer pool. Keep original parts when possible, document installations with photos, and retain all receipts. Most buyers appreciate quality upgrades that enhance appearance without compromising functionality.
