Frequently Asked Questions About International 4700-4900 Frame Nut Covers

What years and models are these frame nut covers compatible with?

These frame nut covers are designed specifically for International 4700 and 4900 series trucks manufactured from 1989 through 2002. They fit the standard frame rail mounting points on both single and tandem axle configurations. Please note that some aftermarket modifications to your frame rails may affect fitment. We recommend measuring your existing nut size before ordering to ensure proper compatibility.

Are these covers made from chrome-plated steel or plastic chrome?

Our International 4700-4900 frame nut covers are available in both materials. The premium options feature heavy-duty chrome-plated steel construction with a triple-chrome plating process for maximum durability and shine. We also offer ABS plastic versions with a chrome finish that provide excellent appearance at a lower price point. Both options are clearly labeled in the product descriptions so you can choose based on your needs and budget.

How many covers come in a set and what hardware is included?

Most sets include either 10 or 20 pieces, depending on the specific product you select. The quantity needed varies based on your truck configuration - single axle models typically require 10-12 covers while tandem axle trucks need 16-20 covers. Installation hardware is not included as these covers are designed to fit over your existing frame nuts. They feature a press-fit design that snaps securely onto standard 1-1/8 inch or 1-1/4 inch hex nuts.

Will these stay on during highway driving and car washes?

When properly installed on clean, rust-free nuts, these covers are designed to withstand normal highway speeds and automatic car washes. The internal retention tabs grip the nut securely. However, excessive rust, grease, or damaged threads on your existing nuts can compromise the fit. We recommend cleaning your frame nuts with a wire brush and degreaser before installation for the most secure attachment.

Can these be removed and reinstalled for maintenance?

Yes, these frame nut covers can be removed for maintenance and reinstalled. The plastic versions can be carefully pried off with a flat-blade screwdriver. Chrome steel covers may require more care during removal to avoid bending. For trucks requiring frequent frame access, we recommend the plastic versions as they handle repeated removal better. Always inspect the retention tabs after removal - damaged tabs may require cover replacement to ensure a secure fit.
