International IH Cabover

Frequently Asked Questions About International IH Cabover Parts

What years and models of International IH Cabovers do these parts fit?

Our International IH Cabover parts primarily fit the CO-4000, CO-8190, and Transtar CO-4070B models from 1970 through 1989. The most common applications are for the CO-4070B (1973-1980) and Transtar CO-4070B (1981-1989). Always verify your specific OEM and model year before ordering, as International made running changes throughout production years. If you're unsure about fitment, contact us with your truck's model number and OEM for verification.

Are these replacement bumpers made of chrome-plated steel or stainless steel?

We offer both options depending on your needs and budget. Our chrome-plated steel bumpers feature triple-chrome plating over heavy-gauge steel, providing an authentic factory appearance at a lower cost. Our 304 stainless steel bumpers offer superior corrosion resistance and require less maintenance, though they have a slightly different shine than chrome. Chrome bumpers typically need re-chroming after 5-7 years of exposure, while stainless steel maintains its appearance with simple polishing.

Do I need special brackets or hardware to install these bumpers?

Most replacement bumpers use your existing mounting brackets and hardware, but these 40+ year old parts are often damaged or missing. We recommend inspecting your current brackets for cracks, rust, or bent mounting points before installation. New Grade 8 mounting bolts are essential - never reuse old hardware. Some installations require bumper-to-frame spacers or shims to achieve proper alignment, especially if your truck has had previous collision damage. Complete hardware kits are available separately.

What's the difference between the standard and Texas-style square bumpers?

Standard International IH Cabover bumpers feature the factory wraparound design with integrated step plates and tow pin holes. Texas-style square bumpers are aftermarket heavy-duty options with a straight-across design, typically 12-14 inches tall, and often include additional mounting points for accessories. Texas bumpers provide more protection but change the truck's appearance significantly. They also typically add 30-40 pounds over factory-style bumpers and may require drilling new mounting holes.

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

Installation typically takes 2-4 hours with basic tools. You'll need a socket set (including 3/4" and 7/8" sockets), breaker bar, penetrating oil, and ideally a helper due to bumper weight (60-80 lbs). The biggest challenge is usually removing old, rusted bolts - plan extra time for this. Front bumper alignment can be tricky on CO-4070B models due to the curved design. We recommend having shims ready and checking hood-to-bumper clearance before final tightening. Professional installation runs $200-400 if you prefer not to DIY.
