Frequently Asked Questions About International 9300/9370 Frame Nut Covers

What are the exact model years these frame nut covers fit?

These frame nut covers are designed specifically for International 9300 and 9370 models manufactured from 1987 through 2003. They fit the standard 33mm lug nuts used on these trucks during this production period. If your truck has been modified with aftermarket wheels or different lug nut sizes, you'll need to verify your current lug nut dimensions before ordering.

Are these covers made of plastic or metal, and how durable are they?

Our International 9300/9370 frame nut covers are available in both ABS plastic and stainless steel options. The ABS plastic covers feature a chrome-plated finish and are impact-resistant for everyday use. The stainless steel versions offer superior durability and corrosion resistance, making them ideal for harsh weather conditions or heavy-duty applications. Both materials are designed to withstand road vibration and temperature extremes.

Do I need any special tools to install these, and will they stay on at highway speeds?

Installation requires no special tools - these covers are designed to push on securely over your existing lug nuts. For best results, clean your lug nuts thoroughly before installation and ensure they're free of rust or debris. The covers feature internal retention tabs that grip the lug nut firmly. Many drivers report no issues at highway speeds, though we recommend checking them during regular pre-trip inspections and applying a small amount of adhesive for added security if desired.

What finish options are available, and do they match OEM chrome?

We offer three primary finishes: chrome-plated, polished stainless steel, and powder-coated options in various colors including black, red, and blue. The chrome-plated versions closely match OEM chrome bumpers and accessories. The polished stainless steel provides a mirror-like finish that won't rust or peel. Powder-coated options are ideal for creating a custom look or matching other colored accessories on your truck.

How many covers come in a set, and do they fit both front and rear wheels?

Sets are available in packages of 10, 20, or 60 pieces. Most International 9300/9370 trucks require 60 total covers for all wheels (10 per wheel x 6 wheels). The covers are universal for both front and rear wheels as long as the lug nut size is consistent. We recommend purchasing a few extra covers as spares, especially if you frequently remove wheels for maintenance or tire changes.
