Frequently Asked Questions About Kenworth W900B/W900L Hood Replacement Parts

Will these hood parts fit both W900B and W900L models, and what years are compatible?

Most hood replacement parts are designed to fit both W900B (1987-2002) and W900L (1987-present) models due to their similar hood designs. However, there are subtle differences between model years, particularly in mounting points and hardware. Always verify compatibility by checking your truck's VIN and model year against the part specifications. Pre-1987 models and post-2007 W900L trucks may have different mounting configurations that require specific parts.

What's the difference between fiberglass and steel hood parts, and which should I choose?

Fiberglass parts are lighter (reducing front axle weight by 50-100 lbs), more resistant to corrosion, and easier to repair minor damage. Steel parts offer superior durability against impacts, better fitment consistency, and maintain original factory specifications. Choose fiberglass for weight savings and corrosion resistance in salt-heavy regions. Select steel for maximum durability and if you frequently operate in harsh conditions with debris exposure.

Do I need special tools or professional installation for hood hinges and latches?

Basic hood latch replacements typically require standard hand tools and 1-2 hours of labor. However, hood hinge replacement is more complex, requiring proper alignment tools, a helper to support the hood weight (150-300 lbs), and potentially welding for certain mounting brackets. Many drivers report alignment issues when installing hinges without proper jigs. We recommend professional installation for hinges unless you have experience with heavy truck bodywork.

Are aftermarket hood grilles and emblems direct bolt-on replacements?

Most quality aftermarket grilles are designed as direct replacements using existing mounting holes. However, some custom or upgraded grilles may require minor drilling or bracket modifications. Original Kenworth mounting clips often break during removal, so order replacement hardware with your grille. Chrome and stainless steel options typically use the same mounting points but may have slightly different clip styles depending on the manufacturer.

How can I ensure proper hood alignment after replacing multiple components?

Start by replacing one component at a time when possible, using the existing parts as alignment references. Critical measurements include the gap between hood and cowl (typically 3/8" to 1/2"), door-to-hood alignment, and ensuring the hood sits level when closed. Adjustment points are built into most hinges and latches - expect to spend 30-45 minutes fine-tuning after installation. Having factory service manual measurements for your specific year model significantly helps achieve proper alignment.
