Frequently Asked Questions About Kenworth W900B/W900L Grille Guards

Will these grille guards fit my specific year and model Kenworth W900?

Most of our grille guards are designed to fit Kenworth W900B models from 1987-2004 and W900L models from 1990-2010. However, fit can vary based on your specific truck configuration, including hood type (curved or flat top), bumper style, and any aftermarket modifications. We recommend checking the product specifications for each grille guard or contacting our support team with your VIN number to ensure proper fitment before ordering.

What's the difference between aluminum and stainless steel grille guards, and which should I choose?

Aluminum grille guards typically weigh 40-60% less than stainless steel options, making them ideal if weight is a concern for your application. They resist corrosion well but may show scratches more easily. Stainless steel guards offer superior durability and impact resistance, maintain their polish better over time, and provide maximum protection in heavy-duty applications. Choose aluminum for weight savings and everyday protection, or stainless steel for maximum durability and professional appearance.

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

Installation typically takes 2-4 hours and requires basic hand tools including socket wrenches, drill with metal bits, and possibly a grinder for minor adjustments. Most grille guards mount using existing bumper bolt holes, though some models may require drilling 2-4 additional mounting holes. The most challenging aspect is usually the weight of the guard itself - we strongly recommend having a second person assist with positioning and mounting. Detailed instructions are included with each guard.

What finish options are available, and how do they hold up over time?

Common finishes include mirror polish, brushed, powder coated black, and chrome. Mirror polish stainless requires regular cleaning to maintain its appearance but offers the classic big rig look. Brushed finishes hide minor scratches better and require less maintenance. Powder coated options provide excellent corrosion resistance and durability but may chip if impacted by road debris. Chrome finishes look exceptional but require the most maintenance and can peel if the base metal is damaged.

Will adding a grille guard affect my headlight beam pattern or airflow to the radiator?

Properly designed grille guards should not significantly impact your headlight beam pattern, as they're engineered with appropriate clearances. However, some drivers report minor shadowing with certain designs. Regarding airflow, most quality guards are designed with adequate spacing between bars to maintain proper radiator cooling. In extreme heat conditions or when pulling heavy loads, monitor your temperature gauges after installation. If cooling becomes an issue, guards with wider bar spacing or removable center sections are available.
