Frequently Asked Questions About Peterbilt 330/335/337 Windshield Accessories
Will these windshield accessories fit my specific Peterbilt 330, 335, or 337 model year?
Most windshield accessories for Peterbilt 330, 335, and 337 models are designed to fit trucks manufactured from 2005 to present. However, there were minor cab design changes in 2011 that may affect fitment of certain accessories like sun visors and wind deflectors. Always verify compatibility by checking your truck's build date and comparing it with the product specifications. If you're unsure, contact us with your OEM number and we can confirm exact fitment.
What's the difference between OEM and aftermarket windshield wipers for these models?
OEM wipers typically use a 22-inch driver side and 22-inch passenger side configuration with J-hook attachments. Aftermarket options often provide better durability with silicone blades that last 2-3 times longer than standard rubber, especially in extreme weather conditions. The main consideration is ensuring you get the correct attachment type - most 330/335/337 models use the standard J-hook, but some specialty configurations may have pin-type connections.
How difficult is it to install bug deflectors and sun visors on these trucks?
Bug deflector installation typically takes 30-45 minutes and requires no drilling on most models - they attach using existing mounting points or 3M automotive tape. Sun visors can be more involved, often requiring 1-2 hours and basic hand tools. The most common challenge is accessing the mounting points behind the cab trim. We recommend having a second person help position larger accessories during installation to prevent damage to the windshield or paint.
What materials and finishes are available for windshield accessories?
Bug deflectors come in smoke-tinted acrylic, clear polycarbonate, and chrome-plated ABS plastic. Sun visors are typically available in polished stainless steel or fiberglass. For durability, stainless steel visors resist rust better in salt-prone areas, while fiberglass options provide the best color matching but may require more maintenance. Acrylic bug deflectors offer good impact resistance but can yellow over time with UV exposure.
Do windshield accessories affect visibility or create wind noise?
Properly installed bug deflectors actually improve visibility by redirecting airflow to keep bugs and debris off your windshield. However, poorly fitted or loose accessories can create whistling at highway speeds. Sun visors may slightly reduce upward visibility but significantly cut glare during sunrise/sunset driving. To minimize wind noise, ensure all mounting hardware is properly tightened and use the provided rubber gaskets or edge trim. Most quality accessories are wind-tunnel tested to minimize noise at speeds up to 75 mph.
