Kenworth W900A Exterior Parts

Frequently Asked Questions About Kenworth W900A Exterior Parts

What years do your W900A exterior parts fit, and how do I know if they'll work with my specific model?

Our W900A exterior parts are designed to fit Kenworth W900A models from 1961 through 1985. However, there were several design changes throughout production. Parts for 1961-1966 models often differ from 1967-1985 versions, particularly in grille styles and hood configurations. To ensure compatibility, check your truck's OEM plate for the exact year and compare it with our product descriptions. If you're unsure, contact us with your OEM and we'll verify fitment before you order.

What's the difference between chrome, stainless steel, and aluminum bumpers for my W900A?

Chrome-plated steel bumpers offer the classic mirror finish but require regular maintenance to prevent rust and pitting. They're typically the heaviest option at 80-120 pounds. Stainless steel bumpers resist corrosion better and maintain their appearance with less upkeep, though they have a slightly different shine than chrome. Aluminum bumpers are the lightest option at 40-60 pounds, won't rust, and can be polished to a high shine, but they're more prone to denting. For trucks in salt-heavy regions or humid climates, stainless steel provides the best long-term value.

Do I need special tools or professional installation for W900A bumpers and grilles?

Most W900A bumpers can be installed with standard shop tools including socket wrenches, torque wrenches, and a floor jack or helper for support. Bumper installation typically takes 2-4 hours. You'll need grade 8 bolts (usually included) and should torque to 120-150 ft-lbs. Grille installation is more straightforward, requiring basic hand tools and about 1-2 hours. The main challenge is alignment - having a second person helps significantly. Professional installation runs $200-400 but isn't necessary if you have basic mechanical skills.

Why are some W900A hoods and fenders significantly more expensive than others?

Price differences reflect material quality and manufacturing methods. Aftermarket fiberglass hoods cost $1,500-4,500 but provide superior durability and authentic appearance. Hand-laid fiberglass parts fit better than chopped mat versions but cost more.

What's the most common fitment issue with aftermarket W900A parts, and how can I avoid it?

The most frequent problem is hood-to-fender gap alignment, especially with aftermarket fiberglass parts. These parts often require adjustment of hood hinges, shimming, or minor trimming for proper fit. To minimize issues, buy hood and fenders from the same manufacturer when possible, as they're designed to work together. Allow for 4-8 hours of adjustment time during installation. Pre-1967 W900A models have different mounting points than later versions, so double-check model year compatibility. When ordering painted parts, expect some touch-up work around mounting areas.
