Frequently Asked Questions About Kenworth T660 Deck Plates & Air Line Boxes
What years and models of Kenworth T660 do these deck plates fit?
Our deck plates and air line boxes are designed to fit Kenworth T660 models from 2008 to 2017. However, compatibility can vary based on your specific truck configuration, including whether you have a day cab or sleeper, and any aftermarket modifications. We recommend checking your VIN or contacting our support team with your truck's year and configuration to ensure proper fitment before ordering.
Are these deck plates made from aluminum or stainless steel, and which is better for my application?
We offer both aluminum and stainless steel options. Aluminum deck plates are lighter weight (typically 40-50% lighter than steel), resist corrosion well, and are ideal for weight-conscious operations. Stainless steel deck plates offer superior durability, better resistance to road chemicals and salt, and maintain their finish longer. For trucks operating in harsh winter conditions or coastal areas, stainless steel is recommended. For standard highway use where weight is a concern, aluminum provides excellent value.
Do I need to drill new holes or modify my truck frame to install these deck plates?
Most of our deck plates are designed as direct bolt-on replacements using existing mounting points on your T660. No drilling or frame modifications are typically required for standard installations. The deck plates come with pre-drilled holes that align with factory mounting locations. Installation usually takes 1-2 hours per side with basic hand tools. However, if you're adding air line boxes to a truck that didn't originally have them, some minor drilling may be necessary for the box mounting brackets.
What's the difference between diamond plate and smooth finish options?
Diamond plate (also called tread plate) features raised diamond patterns that provide better traction when stepping on the deck plate, making it safer in wet or icy conditions. This finish also helps hide minor scratches and wear. Smooth finish deck plates offer a sleeker, more streamlined appearance and are easier to polish to a mirror finish. Diamond plate is recommended for drivers who frequently access their deck area, while smooth finish is preferred for show trucks or those prioritizing appearance.
Will aftermarket deck plates affect my truck's resale value or void any warranties?
Quality aftermarket deck plates typically maintain or can even increase your truck's resale value by protecting the frame area from corrosion and damage. Our deck plates are designed to OEM specifications and don't affect any mechanical systems, so they won't void your powertrain or chassis warranties. Many fleet operators actually prefer trucks with upgraded deck plates as they indicate proper maintenance and care. Always keep your original parts if you plan to return the truck to stock configuration.
