Frequently Asked Questions About International 4700-4900 Frame Crossmembers-Covers

Will these crossmembers fit my specific International 4700 or 4900 model year?

Our frame crossmembers are designed to fit International 4700 and 4900 series trucks from 1989 through 2007. However, there are variations between model years, particularly in mounting hole patterns and frame rail widths. We recommend measuring your frame rail spacing and comparing it to the product specifications, or contacting us with your VIN number for exact fitment verification. Pre-2002 models may require different mounting hardware than later years.

What grade of steel are these crossmembers made from, and how thick is the material?

Most of our International 4700-4900 crossmembers are manufactured from either 3/16" or 1/4" thick mild steel, depending on the specific application and load requirements. Heavy-duty options feature 1/4" steel construction with reinforced gussets at stress points. All crossmembers come with a black powder coat finish for corrosion resistance, though some customers choose to apply additional undercoating in high-salt regions.

Do I need to drill new holes or modify my frame to install these crossmembers?

In most cases, our crossmembers are designed to use existing frame holes and bolt patterns. However, some installations may require drilling 1-2 additional holes per side, particularly when replacing damaged or non-standard crossmembers. We include detailed installation diagrams showing exact mounting points. Professional installation typically takes 2-3 hours, and we recommend using Grade 8 bolts (not always included) for secure mounting.

Can these crossmembers support auxiliary equipment like toolboxes or spare tire carriers?

Yes, our reinforced crossmembers can support additional equipment when properly installed. Standard crossmembers can typically handle up to 200-300 pounds of evenly distributed weight, while heavy-duty versions can support 500+ pounds. Many feature pre-drilled mounting points for common accessories. Always verify the combined weight of your equipment and use appropriate mounting hardware to prevent frame stress.

What's the difference between OEM replacement and aftermarket crossmembers for my International?

OEM replacement crossmembers match original factory specifications exactly, ensuring direct fitment without modifications. Aftermarket options often feature upgraded materials or additional mounting points for accessories, but may require minor adjustments during installation. Our aftermarket crossmembers typically cost 30-50% less than OEM parts while meeting or exceeding original strength specifications. Both options include the same powder coat finish and mounting hardware.
