Frequently Asked Questions About Freightliner Century 112/120 Frame Nut Covers
Will these frame nut covers fit my specific Freightliner Century model year?
These frame nut covers are designed to fit Freightliner Century Class 112 and 120 models from 1996 to 2010. They work with the standard frame rail bolt patterns used during these production years. However, if your truck has aftermarket modifications to the frame rails or non-standard bolt spacing, we recommend measuring your bolt pattern before ordering. The standard spacing is typically 24 inches on center for most Century models.
What material are these nut covers made from, and how long will they last?
Most frame nut covers for the Century 112/120 are manufactured from either 304 stainless steel or heavy-duty ABS chrome plastic. Stainless steel options typically last 10-15 years with minimal maintenance, while chrome ABS versions generally last 5-7 years depending on weather exposure and road conditions. Stainless steel resists rust and corrosion better, especially in areas with road salt, but chrome ABS options are more budget-friendly and still provide good protection against the elements.
Do I need to remove my wheels or jack up the truck to install these?
No, you don't need to remove wheels or jack up your truck for installation. Frame nut covers can be installed with the truck on the ground. Installation typically takes 30-45 minutes per side using basic hand tools. You'll need a socket wrench to remove existing nuts, clean the bolt threads, and then install the decorative nut covers. Some drivers find it helpful to use a wire brush to clean threads before installation for easier threading.
What styles and finishes are available, and which looks best?
Frame nut covers come in several popular styles: standard dome (rounded top), pointed bullet style, and flat-top designs. Finish options include mirror-polished stainless, brushed stainless, and chrome-plated plastic. Mirror-polished stainless remains the most popular choice as it matches other chrome accessories and maintains its shine with occasional polishing. The style choice is mainly aesthetic - dome covers provide a classic look, while pointed styles offer a more aggressive appearance.
How many nut covers do I need for a complete set, and are they sold individually?
A complete set for a Freightliner Century 112/120 typically requires 32-40 pieces, depending on your specific frame configuration and wheelbase. Most trucks use 16-20 covers per side. We sell these both as complete sets and individually, allowing you to replace damaged pieces or accommodate custom frame modifications. Count the exposed frame bolts on both sides of your truck before ordering to ensure you get the right quantity.
