Frequently Asked Questions About Kenworth T800 Windshield, Wiper & Roof Accessories

What year models of Kenworth T800 do these windshields and accessories fit?

Most of our windshields and roof accessories are designed to fit Kenworth T800 models from 1987 through 2010. However, there are variations between hood styles (curved hood vs. flat hood) that affect fitment. Always check the specific product description for your exact year and hood configuration. If you're unsure about your truck's specifications, contact us with your VIN number and we'll help verify compatibility.

How difficult is it to install a replacement windshield on my T800, and what tools do I need?

Windshield replacement typically requires two people and takes 2-4 hours. You'll need a windshield removal tool, urethane adhesive and primer, masking tape, and basic hand tools. The most challenging part is removing the old windshield without damaging the cab. We recommend professional installation if you're not experienced with auto glass work, as improper installation can lead to leaks and wind noise. Wiper arms and motors are much simpler DIY projects requiring only basic tools and 30-60 minutes.

What's the difference between OEM and aftermarket windshields for the T800?

OEM windshields use PPG or Pilkington glass with the DOT certification and match factory specifications exactly. Aftermarket options are typically 20-40% less expensive and meet DOT standards but may have slight variations in tint or thickness. Both options fit properly when ordered for the correct year and hood style. The main differences are price and whether you need the Kenworth bug stamp for originality. For daily drivers, quality aftermarket glass performs just as well.

Why do my windshield wipers streak or skip, even after replacing the blades?

Streaking often indicates worn wiper arms that don't apply consistent pressure across the blade. T800 wiper arms typically need replacement every 3-5 years due to spring tension loss. Also check that you're using the correct 22-inch heavy-duty blades designed for commercial trucks. Standard automotive blades won't hold up. If new arms and blades still streak, the windshield may have mineral deposits or micro-scratches that need polishing with glass restoration compound.

What roof accessories help reduce wind noise and improve aerodynamics on the T800?

Wind deflectors and roof fairings are the most effective upgrades for reducing cab noise and improving fuel economy. Full roof fairings can improve MPG by 5-7% at highway speeds. For T800s without sleepers, cab extenders help smooth airflow between the cab and trailer. Sun visors also reduce wind buffeting while blocking glare. When selecting these accessories, ensure they match your specific cab configuration (day cab, flat top sleeper, or raised roof) for proper fitment and maximum benefit.
