Frequently Asked Questions About Peterbilt 330, 335, and 337 Grille Guards

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

Most Peterbilt 330, 335, and 337 grille guards are designed to fit select 2005 and newer Peterbilt 330/335/337 medium-duty truck models. Exact fitment can vary by model year, hood style, axle configuration, bumper type, and mounting location.

Before ordering, check the product fitment details for the specific grille guard. If you are unsure, verify your truck?s model year, bumper style, and existing mounting points before purchase.

What are Peterbilt 330/335/337 grille guards made from?

Peterbilt 330/335/337 grille guards are commonly made from heavy-duty steel, stainless steel, or aluminum, depending on the product design. Steel grille guards offer strong front-end protection and are often powder-coated or chrome-plated for corrosion resistance. Aluminum grille guards provide lighter-weight protection while still helping shield the front of the truck from road debris and minor impacts.

Common material options may include 14-gauge to 10-gauge steel, polished stainless steel, chrome-plated steel, black powder-coated steel, or bare aluminum.

Can I install a Peterbilt 330/335/337 grille guard myself?

Many Peterbilt 330/335/337 grille guards can be installed with standard shop tools and basic mechanical experience. Installation usually requires mounting the grille guard to the truck?s frame rails, bumper area, or existing mounting points.

Typical tools may include wrenches, sockets, a drill, and mounting hardware. Because grille guards can weigh 75 to 150 pounds, a second person or lifting support may be needed during installation. Professional installation is recommended if drilling, alignment, or heavy front-end mounting is required.

What styles and finishes are available for Peterbilt 330/335/337 grille guards?

Peterbilt 330/335/337 grille guards are available in several styles, including horizontal bar grille guards, heavy-duty channel-style guards, and lighter tube-style guards. Some grille guards may also include light mounting tabs, tow hook openings, or integrated screen protection.

Common finish options include mirror-polished stainless steel, chrome-plated steel, black powder coat, and aluminum. Choose a finish based on your preferred truck appearance, corrosion resistance needs, and the level of front-end protection required.

Will a grille guard affect my Peterbilt warranty or insurance?

Installing an aftermarket grille guard on a Peterbilt 330, 335, or 337 typically does not void the truck?s warranty by itself because a grille guard is a bolt-on exterior accessory. However, damage caused by improper installation, incorrect mounting, drilling errors, or product misuse may not be covered by the truck manufacturer or parts warranty.

Insurance rules vary by provider. Some insurance companies may treat grille guards as protective accessories, while others may require documentation after installation. Check with your insurance carrier to confirm whether the grille guard should be added to your policy or equipment records.
