Frequently Asked Questions About Kenworth T680 Frame Nut Covers

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

Most Kenworth T680 frame nut covers are manufactured from either chrome-plated ABS plastic or 304 stainless steel. The chrome-plated ABS options are lightweight, won't rust, and maintain their shine with minimal maintenance. Stainless steel versions offer superior durability and resistance to road chemicals, though they may show minor surface oxidation in extreme conditions. Both materials are designed to withstand typical highway conditions including salt, moisture, and temperature extremes.

Will these nut covers fit my specific T680 model year and wheel configuration?

Frame nut covers for the T680 are generally compatible with model years 2013-present, fitting standard 33mm hex nuts commonly found on the frame rails. However, trucks with aftermarket wheels or specialty suspension setups may require verification of nut size. Most covers are designed for standard 10-lug hub-piloted wheel systems. We recommend measuring your specific nut size before ordering, as some fleet-spec trucks may have non-standard hardware.

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

Installation is straightforward and typically takes 30-45 minutes for a complete set. Most frame nut covers either push-fit directly onto the nuts or use a twist-lock design that requires no tools. Some models include small set screws that need a standard Allen wrench. The main challenge drivers report is accessing nuts behind the fuel tanks or other frame-mounted components. Having a creeper and good lighting makes the job much easier. No drilling or permanent modifications are required.

What styles and finishes are available, and which looks best with my truck?

Frame nut covers come in several popular styles including classic dome, pointed bullet, and flat-top designs. Finish options typically include mirror-polished chrome, brushed stainless, and powder-coated colors like black or red. Chrome remains the most popular choice for trucks with existing chrome accessories. For blacked-out builds, the powder-coated options provide a cohesive look. Consider matching your choice to existing wheel accessories like lug nut covers or hub caps for a coordinated appearance.

How many nut covers do I need for a complete set, and are they sold individually?

A standard Kenworth T680 typically requires 20-24 frame nut covers for complete coverage of the visible frame rail nuts, though this can vary based on wheelbase and suspension configuration. Most retailers sell them in sets of 10 or 20, with individual pieces available for replacements. Count the exposed nuts on both frame rails before ordering. Don't forget to check for any additional nuts near the fifth wheel area or auxiliary equipment mounting points if you want complete coverage.
