Frequently Asked Questions About Peterbilt 330/335/337 Grille Guards

Will these grille guards fit my specific year model Peterbilt 330, 335, or 337?

Most grille guards for the Peterbilt 330/335/337 series are designed to fit model years 2005 and newer. However, there can be variations based on your truck's specific configuration, such as hood style (set-back or set-forward axle) and bumper type. We recommend checking the product specifications for each grille guard or contacting our customer service team with your VIN number to ensure proper fitment before ordering.

What materials are these grille guards made from, and how durable are they?

Our Peterbilt 330/335/337 grille guards are typically constructed from heavy-duty steel (ranging from 14-gauge to 10-gauge) or aluminum, depending on the model. Steel guards offer maximum protection and are powder-coated or chrome-plated for corrosion resistance. Aluminum options provide excellent durability with less weight. Both materials are designed to withstand road debris, minor impacts, and harsh weather conditions common in commercial trucking applications.

Can I install a grille guard myself, or do I need professional installation?

Installation complexity varies by model, but most grille guards can be installed with basic tools and mechanical knowledge. Typical installation takes 2-4 hours and requires drilling into the frame rails or using existing mounting points. You'll need standard tools like wrenches, a drill, and possibly a helper due to the weight (usually 75-150 lbs). Detailed instructions are included with each guard, but if you're not comfortable with the installation, we recommend professional installation to ensure proper mounting and safety.

What styles and finishes are available for these grille guards?

Peterbilt 330/335/337 grille guards come in several styles including traditional horizontal bar designs, heavy-duty channel designs, and lighter-weight tube styles. Common finishes include mirror-polished stainless steel, chrome-plated steel, black powder coat, and bare aluminum (which can be polished or painted). Some models also feature additional options like light mounting tabs, tow hook cutouts, or integrated bug screens. The style you choose should match both your aesthetic preferences and functional needs.

Will adding a grille guard affect my truck's warranty or insurance?

Installing an aftermarket grille guard typically does not void your Peterbilt warranty, as it's considered a bolt-on accessory that doesn't modify the vehicle's original components. However, any damage caused by improper installation would not be covered. Regarding insurance, most carriers view grille guards as protective equipment that can reduce damage claims. We recommend notifying your insurance company after installation, as some offer discounts for protective accessories, while others may require documentation for coverage purposes.
