Frequently Asked Questions About Volvo VNL Gen II Deck Plates & Air Line Boxes
What years and models are these deck plates compatible with?
These deck plates and air line boxes are specifically designed for Volvo VNL Generation II trucks, which includes model years 2018 and newer. They will fit all VNL 300, 400, 640, 740, and 860 series trucks manufactured after the 2018 redesign. These parts are not compatible with pre-2018 VNL models due to significant chassis and frame design changes.
Are these deck plates made from stainless steel or chrome-plated steel?
Most deck plates in this category are available in both 304-grade stainless steel and chrome-plated steel options. Stainless steel versions offer superior corrosion resistance and require less maintenance, while chrome-plated options provide a mirror finish at a lower price point. Product descriptions specify the material for each item. For trucks operating in harsh winter conditions with road salt exposure, we recommend stainless steel for longevity.
Do I need to drill new holes or modify my truck for installation?
The majority of our deck plates are designed as direct bolt-on replacements using existing mounting points on your VNL Gen II. No drilling or modifications are typically required. Installation usually takes 30-60 minutes per side with basic hand tools. Some custom or full-coverage deck plate sets may require minor drilling for additional mounting points, which will be clearly noted in the product description.
What's included with the air line box assemblies?
Air line box assemblies typically include the box housing, mounting brackets, and necessary hardware for installation. However, air lines, glad hands, and electrical connections are sold separately unless specifically stated as a complete kit. Most boxes feature spring-loaded doors and rubber seals to protect connections from weather and road debris. Check individual product listings for exact contents.
Will aftermarket deck plates affect my warranty or DOT compliance?
Properly installed deck plates and air line boxes that don't modify the truck's structure or safety systems generally won't affect your warranty. These are considered cosmetic accessories. All our deck plates maintain proper ground clearance and don't interfere with DOT-required lighting or reflectors. However, always ensure air line boxes allow proper glad hand accessibility for pre-trip inspections to maintain DOT compliance.
