Peterbilt 330/335/337 Windshield, Wiper & Roof Acc

Frequently Asked Questions About Peterbilt 330/335/337 Windshield, Wiper & Roof Accessories

What years and models are these windshield and wiper accessories compatible with?

These accessories are designed specifically for Peterbilt 330, 335, and 337 models from 2005 to current production years. Most windshield components fit all three models interchangeably since they share the same cab design. However, always verify your specific truck's OEM and production year before ordering, as minor variations can occur in pre-2008 models. For exact fitment, check the individual product descriptions or contact our support team with your truck's details.

Are the windshields OEM quality, and what's the difference between aftermarket and genuine Peterbilt glass?

We carry both OEM-equivalent and genuine Peterbilt windshields. Our aftermarket options meet DOT standards and use the same glass thickness (typically 6mm laminated safety glass) as factory windshields. The main differences are price and minor details like tinting options. Genuine Peterbilt glass includes the manufacturer's logo and typically costs 30-40% more. Both options fit identically and include the same UV protection and acoustic dampening properties. Most customers choose aftermarket for routine replacements unless insurance specifically requires OEM.

How difficult is it to install wiper arms and blades, and what tools are needed?

Wiper arm and blade installation is straightforward and typically takes 15-30 minutes. You'll need a 13mm or 15mm socket (depending on your model year), a small flathead screwdriver for the arm caps, and potentially a wiper arm puller for stubborn removals. The most common mistake is forcing the arms off without first removing the retaining nut completely. Always mark the arm position on the windshield with tape before removal to ensure proper sweep alignment during reinstallation.

What roof accessories fit the Peterbilt 330/335/337, and are there weight restrictions?

Popular roof accessories include cab lights, light bars, air horns, and antenna mounts. The 330/335/337 cab roof can safely support up to 150 pounds of evenly distributed weight. Most light bars and standard accessories fall well under this limit. Pre-drilled mounting points are available on most models post-2010. For older trucks or custom installations, roof reinforcement plates are recommended for accessories over 50 pounds or those creating significant wind resistance.

Why are my new wiper blades streaking, and which blade type works best for these trucks?

Initial streaking often occurs due to shipping residue on new blades or windshield contamination. Clean both the windshield and new blades with isopropyl alcohol before installation. For Peterbilt 330/335/337 models, we recommend heavy-duty beam-style blades over traditional frame blades, as they maintain better contact pressure across the curved windshield. The standard sizes are 22" for both driver and passenger sides on most model years. Winter blades with rubber boots are essential in snow-prone areas to prevent ice buildup.
