Frequently Asked Questions About Kenworth T660 Windshield, Wiper & Roof Accessories

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

Our Kenworth T660 windshield, wiper, and roof accessories are designed specifically for T660 models manufactured from 2008 to 2015. While many parts are universal across all T660 production years, some accessories like wiper motor assemblies may vary between early models (2008-2011) and later models (2012-2015). Always check the product description for specific year compatibility, or contact our support team with your VIN for exact fitment confirmation.

How difficult is it to install aftermarket windshield trim and roof accessories?

Most windshield trim pieces and roof accessories can be installed with basic hand tools in 30-60 minutes. Windshield trim typically uses adhesive backing or clips that snap into existing mounting points. However, windshield replacement itself requires professional installation due to safety concerns and proper sealing requirements. Wiper arm and blade replacements are straightforward DIY jobs that take about 10-15 minutes. For roof-mounted accessories like visors or marker lights, you may need to drill mounting holes, so we recommend having installation instructions handy or consulting a professional if you're not comfortable with bodywork.

What's the difference between OEM and aftermarket windshield wipers for the T660?

OEM wipers typically cost 40-60% more than quality aftermarket options but offer guaranteed fitment and original equipment durability. Aftermarket wipers from reputable brands like ANCO or Trico provide comparable performance at a lower price point. The main differences are in the attachment mechanisms - some aftermarket wipers use universal adapters while OEM parts have model-specific connectors. For T660s, we recommend heavy-duty beam-style wipers rated for commercial use, as they handle highway speeds and weather extremes better than conventional frame wipers.

Are stainless steel and chrome windshield accessories worth the extra cost?

Stainless steel and chrome accessories typically cost 30-50% more than standard painted options but offer superior corrosion resistance and longevity. For trucks operating in harsh weather conditions or coastal areas with salt exposure, stainless steel trim pays for itself by lasting 3-5 times longer than painted alternatives. Chrome provides an excellent mirror finish but requires more maintenance to prevent pitting. If your truck sees primarily highway miles in moderate climates, quality painted accessories offer good value. Consider your operating environment and how long you plan to keep the truck when making this decision.

What should I look for when replacing windshield rubber seals and gaskets?

Quality windshield seals should be made from EPDM rubber that remains flexible in extreme temperatures (-40?F to 200?F). Look for seals with integrated steel or aluminum cores for proper shape retention. Cheap rubber seals often shrink, crack, or lose elasticity within 1-2 years, leading to water leaks and wind noise. OEM-specification seals typically feature precise molding that matches your T660's windshield channel perfectly. When purchasing, verify the seal includes any necessary adhesive strips or butyl tape for proper installation. A quality seal should last 5-7 years under normal conditions.
