Kenworth W900B/W900L Parts

Frequently Asked Questions About Kenworth W900B/W900L Parts

Will these bumpers fit my specific year W900B or W900L, and what are the key differences between models?

W900B bumpers typically fit models from 1987-2010, while W900L bumpers fit 1988-present models. The main difference is the hood length - W900B has a 119" BBC (Bumper to Back of Cab) while W900L has a 130" BBC. Most bumpers are interchangeable between the two models, but always verify the specific part number matches your truck's year. Pre-2007 models may have different mounting hole patterns than 2007+ models due to emission regulation changes.

What gauge steel are these bumpers made from, and how do they compare to OEM quality?

Our aftermarket bumpers are typically made from 16-gauge or 14-gauge steel, with premium options in 12-gauge. OEM Kenworth bumpers are usually 14-gauge. The 16-gauge options work well for standard applications, while 14-gauge and 12-gauge provide extra durability for heavy-duty use or frequent loading dock contact. All options include proper reinforcement channels and mounting brackets that match or exceed OEM specifications.

Do I need special tools or professional installation, and how long does installation typically take?

Basic hand tools are sufficient for most installations - you'll need socket wrenches (typically 3/4" and 7/8"), a torque wrench, and possibly a drill for aftermarket accessories. Installation takes 2-4 hours for experienced mechanics, or 4-6 hours for first-timers. The bumper weighs 80-120 pounds, so VIN a helper is strongly recommended. Some custom or heavy-duty bumpers may require minor drilling or bracket adjustments.

What finish options are available, and how do they hold up against rust and road chemicals?

We offer chrome-plated, polished stainless steel, and painted finishes. Chrome provides the classic look but requires regular maintenance to prevent pitting. Stainless steel (304 grade) offers the best corrosion resistance with minimal maintenance. Painted bumpers come with automotive-grade primer and paint but may need touch-ups after 2-3 years of heavy use. For salt-heavy regions, we recommend stainless steel or applying additional undercoating to chrome bumpers.

Can I add accessories like fog lights or air dam panels to these bumpers?

Most W900B/W900L bumpers come pre-drilled for standard accessories or include knockout panels for easy customization. Common fog light mounting requires 4" or 4.5" round openings. Air dam panels typically bolt directly to existing holes. For bumpers without pre-drilled holes, use a step drill bit and follow the template included with your accessories. Always check weight ratings - standard bumpers support up to 50 pounds of additional accessories without reinforcement.
