Frequently Asked Questions About Peterbilt 567/579 Frame Nut Covers

What material are these frame nut covers made from, and will they rust or corrode?

Our Peterbilt 567/579 frame nut covers are manufactured from either chrome-plated ABS plastic or 304 stainless steel, depending on the specific model you choose. The chrome-plated ABS options provide excellent durability and won't rust, though they may show wear over time in harsh conditions. The stainless steel versions offer superior corrosion resistance and longevity, making them ideal for trucks exposed to road salt, chemicals, or coastal environments. Both materials are designed to withstand typical highway conditions and maintain their appearance with basic maintenance.

Will these nut covers fit my specific Peterbilt 567 or 579 model year?

These frame nut covers are designed to fit Peterbilt 567 models from 2013 to current and Peterbilt 579 models from 2012 to current. The covers are engineered to fit standard 33mm lug nuts, which are factory standard on these models. However, if your truck has aftermarket wheels with different lug nut sizes, you'll need to verify the nut dimensions before ordering. Most covers in this category are universal within these model years, but always check the product specifications for any model-specific variations.

How difficult is the installation, and what tools do I need?

Installation is straightforward and typically takes 30-45 minutes for a complete set. No special tools are required - the covers either push on with a friction fit or thread on, depending on the style. For push-on models, ensure the lug nuts are clean and free of debris for the best fit. Some drivers use a rubber mallet for a secure fit, though hand pressure is usually sufficient. Thread-on models simply screw onto the existing lug nuts. No removal of wheels or tires is necessary, making this a simple upgrade you can do in your driveway or shop.

What styles and finishes are available, and which looks best?

Frame nut covers come in several popular styles including pointed, rounded dome, and flat-top designs. Finish options typically include chrome, stainless steel, and colored versions (red, blue, black). Chrome provides the classic shiny look but requires more maintenance. Stainless steel offers a similar appearance with less upkeep. Pointed styles create an aggressive look, while dome styles offer a more refined appearance. The best choice depends on your truck's overall style - pointed works well with custom builds, while dome styles complement stock or fleet trucks.

How many nut covers do I need for my truck, and are they sold in sets?

A standard Peterbilt 567/579 with dual rear wheels typically requires 30 nut covers total: 10 for each front wheel (20 total) and 5 for each outer rear wheel (10 total). Most are sold in sets of 10, so you'll need to order 3 sets for complete coverage. Some suppliers offer complete truck sets at a discount. If you're only covering the front wheels or outer rears for appearance, adjust your quantity accordingly. Always count your specific truck's lug nuts before ordering, as some custom wheel configurations may vary.
