Frequently Asked Questions About Peterbilt 367 Frame Nut Covers

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

Most Peterbilt 367 frame nut covers are manufactured from either 304 stainless steel or chrome-plated ABS plastic. Stainless steel options offer superior durability and won't rust, though they may show minor surface oxidation over time that can be easily polished out. Chrome-plated plastic covers are lighter and more affordable but may show wear or pitting after 2-3 years of heavy road use, especially in areas with road salt exposure. For maximum longevity in harsh conditions, we recommend stainless steel covers.

Will these frame nut covers fit my specific year Peterbilt 367?

Peterbilt 367 frame nut covers are designed to fit models from 2007 to present, as the frame rail spacing and bolt patterns have remained consistent. However, you'll need to verify your specific bolt size before ordering. Most 367 models use either 33mm or 1-5/16" lug nuts, though some specialty configurations may vary. We recommend measuring your existing lug nuts with calipers or checking your truck's spec sheet to ensure proper fitment. Custom axle configurations or aftermarket wheels may require different sizing.

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

Installation is straightforward and typically takes 30-45 minutes for a complete set. No special tools are required beyond what you'd use for regular wheel maintenance. Simply remove your wheels, slide the covers over your existing lug nuts, and reinstall the wheels. The covers are designed with a friction-fit system that keeps them secure without additional hardware. Some drivers report that applying a small amount of anti-seize compound inside the covers helps with future removal if needed.

What styles and finishes are available for the Peterbilt 367?

Frame nut covers for the 367 come in several popular styles: standard dome covers for a clean look, pointed "spike" styles for an aggressive appearance, and flanged versions that extend slightly over the wheel rim edge. Finish options typically include mirror-polished chrome, brushed stainless, and powder-coated black. Some manufacturers also offer colored options like candy red or blue. The style you choose won't affect fitment, so selection comes down to matching your truck's existing chrome accessories and personal preference.

How do these covers hold up to tire changes and regular maintenance?

Quality frame nut covers are designed to withstand repeated removal during tire rotations and brake service. The key is proper removal technique - always pull covers straight off rather than prying at an angle, which can deform the opening. Most professional drivers report getting 5-7 years of regular use from stainless steel covers with proper care. Keep a spare or two in your tool box, as covers can occasionally get lost during roadside tire changes. Regular cleaning with chrome polish helps maintain appearance and makes removal easier during service.
