Frequently Asked Questions About Peterbilt 387 Deck Plates & Air Line Boxes
What years of Peterbilt 387 trucks are these deck plates compatible with?
Our deck plates and air line boxes are designed to fit Peterbilt 387 models from 2000 through 2010. While the mounting patterns remained consistent throughout these production years, we recommend verifying your specific truck's configuration before ordering. Models with aftermarket bumpers or custom modifications may require additional fitment verification.
Are these deck plates made from stainless steel or chrome-plated steel?
We carry both options depending on your preference and budget. Our stainless steel deck plates are 304-grade stainless with a mirror polish finish that resists corrosion without requiring replating. Chrome-plated versions feature heavy-duty steel construction with triple-chrome plating. Stainless options typically cost 20-30% more but offer superior longevity in harsh weather conditions.
Do I need to drill new holes or modify my bumper for installation?
Most installations use existing mounting points and require no drilling. Standard deck plates align with factory bolt patterns on OEM bumpers. However, if you have an aftermarket bumper or are replacing damaged mounting brackets, some drilling may be necessary. Each product includes detailed mounting instructions and hardware specifications. Professional installation typically takes 30-45 minutes per side.
What's included with the air line box assembly?
Complete air line box assemblies include the box housing, mounting brackets, rubber glad hand holders, and stainless steel mounting hardware. The boxes accommodate standard glad hand connections and feature drainage slots to prevent water accumulation. Spring-loaded door models include tension springs and hinge pins. Note that air lines and glad hands are sold separately.
How do I maintain the chrome finish on these deck plates?
Chrome deck plates require regular cleaning with non-abrasive chrome polish to maintain their appearance. Avoid using steel wool or harsh chemicals that can damage the plating. For winter driving, rinse road salt off weekly and apply a thin coat of wax monthly. Minor pitting or clouding is normal after 2-3 years of heavy use. Stainless steel options require less maintenance but should still be cleaned regularly with stainless-specific cleaners.
