Frequently Asked Questions About International 9300/9370 Frame Crossmembers-Covers

What is a frame crossmember cover and what does it do on my International 9300/9370?

A frame crossmember cover is a panel that fits over or between the frame rails of your truck, typically in the area behind the cab or under the chassis. It helps conceal wiring, hoses, and hardware running along the frame, gives the underside of the truck a cleaner finished look, and can offer a degree of protection against road debris and moisture for components mounted near the crossmember.

Will this crossmember cover fit my specific International 9300 or 9370 model year?

Frame and crossmember configurations can vary by production year and chassis setup, so it's important to check the listed fitment details on each product page before ordering. If you're not sure whether a cover matches your truck's frame width or mounting points, measure your existing crossmember or cover and compare it to the dimensions listed, or reach out to our team with your VIN or model year for confirmation.

What material and finish options are available for these covers?

Crossmember covers in this category are commonly available in materials like steel and aluminum, with finishes ranging from raw or mill finish to painted or powder-coated options. Steel covers tend to offer added durability, while aluminum options are lighter and naturally more resistant to rust. Check each listing for the specific material and finish so you can choose what best matches your truck's existing components and your budget.

How difficult is it to install a frame crossmember cover myself?

Most crossmember covers are designed to bolt into existing mounting holes on the frame, making installation straightforward for someone comfortable doing basic mechanical work with common hand tools. That said, actual difficulty can depend on the specific cover design and how accessible the mounting points are on your truck. If you're unfamiliar with your truck's frame layout, it may be worth having a qualified shop handle the install to avoid misalignment.

Can a crossmember cover affect wiring, air lines, or other components running along the frame?

Yes, since these covers are installed in the same area where wiring harnesses, air lines, and hydraulic hoses often run, it's important to check clearance before tightening everything down. Make sure no lines are pinched or rubbing against the cover once installed, and periodically inspect the area during routine maintenance to catch any wear caused by vibration or movement over time.
