Frequently Asked Questions About Kenworth W900B/W900L Grilles

What years do these grilles fit, and are W900B and W900L grilles interchangeable?

W900B grilles typically fit models from 1987 to 2010, while W900L grilles fit 1987 to present. The main difference is that W900L grilles are designed for the extended hood model, making them approximately 6 inches longer than W900B grilles. They are not directly interchangeable due to this size difference. Always verify your specific model year and hood length before ordering, as some transitional years may have variations.

What materials are available, and which holds up best against road debris and weather?

Most aftermarket grilles come in either stainless steel or aluminum. Stainless steel grilles offer superior durability against rock chips and corrosion, making them ideal for harsh weather conditions and heavy-duty use. Aluminum grilles are lighter weight and resist corrosion well but may dent more easily from road debris. For maximum longevity, choose 304-grade stainless steel with a polished or powder-coated finish.

How difficult is the installation, and what tools or modifications are required?

Installation typically takes 2-4 hours and requires basic hand tools including socket sets, screwdrivers, and possibly a drill for custom applications. Most grilles use the factory mounting points, but some aftermarket options may require minor drilling or bracket adjustments. The biggest challenge is usually accessing and removing the old grille assembly. Having a second person helps with alignment during installation.

What grille styles are available, and do they affect airflow to the radiator?

Common styles include horizontal bars, vertical bars, punched hole patterns, and custom billet designs. While decorative grilles can slightly reduce airflow compared to stock, reputable manufacturers design their products to maintain adequate cooling. Grilles with larger openings or punched patterns typically provide better airflow than tightly spaced bar designs. For trucks operating in extreme heat or pulling heavy loads, consider styles with maximum open area.

Will aftermarket grilles work with factory-installed bug screens and winter fronts?

Most quality aftermarket grilles are designed to accommodate standard bug screens and winter fronts, but compatibility can vary by manufacturer. Grilles that use factory mounting points typically work with OEM accessories. Custom or heavily modified grilles may require aftermarket bug screens specifically designed for that grille style. Always check product specifications or contact us to confirm compatibility with your existing accessories.
