Frequently Asked Questions About Kenworth Cabover Frame Nut Covers
What material are these frame nut covers made from, and will they rust or corrode?
Our Kenworth cabover frame nut covers are manufactured from either chrome-plated steel or 304-grade stainless steel, depending on the specific product you select. Chrome-plated options provide excellent shine and corrosion resistance when properly maintained, while stainless steel versions offer superior long-term durability against rust and road chemicals. Both materials are significantly more durable than painted or plastic alternatives and are designed to withstand harsh trucking conditions.
Which Kenworth cabover models and years are these nut covers compatible with?
These frame nut covers are designed to fit Kenworth K100, K100E, and K123 cabover models from 1963 through 1987. The standard size fits most factory frame bolts, which typically use 1-1/8" or 1-1/4" hex nuts. However, we recommend measuring your specific frame nuts before ordering, as some modified or rebuilt trucks may have non-standard hardware. The covers are not compatible with newer aerodynamic models or conventional Kenworth trucks.
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 - just a standard socket wrench to remove and reinstall your frame nuts. The covers slip over existing nuts, so you'll need to loosen each nut, slide the cover behind it, then retighten. Some drivers prefer to apply a small amount of anti-seize compound during installation to prevent galvanic corrosion between dissimilar metals. No drilling, welding, or modifications to your frame are necessary.
What styles and finishes are available, and how many covers come in a set?
Frame nut covers are available in mirror-polished chrome, brushed stainless steel, and powder-coated black finishes. Style options include smooth dome, pointed cone, and flat-top designs. Sets typically include 10, 20, or 40 pieces, as frame bolt quantities vary by truck configuration and wheelbase. We recommend counting your visible frame nuts before ordering to ensure you purchase the correct quantity. Individual covers are also available for replacement or custom applications.
How do these covers hold up to winter road salt and washing, and what maintenance is required?
Quality frame nut covers are designed to withstand road salt, mag chloride, and regular truck washing when properly maintained. Chrome versions should be polished monthly during winter months to prevent pitting, while stainless steel requires less frequent attention. Regular washing with soap and water, followed by a quick wipe-down, will keep them looking sharp. Avoid using harsh acids or abrasive cleaners. Many drivers report their covers still look great after 5+ years of service with basic maintenance.
