Frequently Asked Questions About Mack CH/CHN/CHU Truck Windshield Accessories

Will these windshield accessories fit my specific Mack CH model year?

Our windshield accessories are designed to fit Mack CH, CHN, and CHU models from 1988 to 2007. However, slight variations exist between early models (1988-1999) and later models (2000-2007), particularly in mounting hole patterns and windshield frame dimensions. We recommend checking your VIN or contacting our support team with your truck's year and model number to ensure proper fitment before ordering.

What's the difference between stainless steel and chrome-plated windshield trim options?

Stainless steel trim offers superior durability and corrosion resistance, making it ideal for trucks operating in harsh weather conditions or coastal areas. It maintains its appearance with minimal maintenance. Chrome-plated options provide a mirror-like finish at a lower price point but require more frequent cleaning and may show wear over time, especially in salt-heavy environments. Both options fit identically, so the choice comes down to your budget and maintenance preferences.

Can I install windshield visors and bug deflectors myself, or do I need professional help?

Most windshield accessories can be installed with basic tools in 30-60 minutes. Sun visors typically require drilling 4-6 mounting holes using the provided template, while bug deflectors often use no-drill clamp systems. You'll need a drill with metal bits, measuring tape, and a helper to hold pieces in place. Professional installation is recommended if you're uncomfortable drilling into your cab or if you're installing multiple accessories that require precise alignment.

Do aftermarket windshield gaskets and seals work as well as OEM parts?

Quality aftermarket windshield gaskets from reputable manufacturers often match or exceed OEM specifications. Look for EPDM rubber gaskets with UV inhibitors that prevent cracking and maintain flexibility in extreme temperatures. Proper installation is critical - even the best gasket will leak if installed incorrectly. Many drivers report better results with aftermarket options that feature improved drainage channels compared to original equipment.

How do exterior sun visors affect fuel economy and wind noise?

Properly designed windshield visors have minimal impact on fuel economy, typically less than 1-2% in real-world conditions. Wind noise is more noticeable at highway speeds, particularly with wider visors. Look for aerodynamic designs with rolled edges and proper mounting brackets that maintain the correct angle. Some drivers report reduced wind noise after adding foam weather stripping between the visor and cab during installation.
