International IH Cabover Exterior Parts

Frequently Asked Questions About International IH Cabover Exterior Parts

What years and models of International Cabover trucks do these exterior parts fit?

Our International IH Cabover exterior parts primarily fit the CO-4000 series (1959-1980), including the CO-4070A, CO-4070B, and Transtar CO-4070 models. Most bumpers and grilles are compatible with both single and tandem axle configurations. For specific year compatibility, check the product description or contact our team with your OEM number. Note that parts for pre-1959 models and the newer 9670 series may require special ordering.

Are these bumpers made from the original steel thickness, or are they thinner reproductions?

Quality varies by manufacturer. Our premium aftermarket bumpers are made from 14-gauge steel, matching or exceeding original specifications. Economy options use 16-gauge steel, which is approximately 25% thinner but still suitable for most applications. Original NOS (New Old Stock) parts, when available, maintain factory specifications. Each product listing clearly states the material thickness and whether it meets OEM standards.

Do I need to drill new mounting holes, or will these parts bolt directly to existing brackets?

Most of our bumpers and exterior parts are designed as direct bolt-on replacements using existing mounting points. However, some aftermarket parts may require minor drilling for accessories like fog lights or air horn brackets. Grille surrounds typically use the original mounting tabs, though corrosion on your existing frame may require cleaning or retapping threads. We recommend having a drill and tap set available during installation.

What's the difference between chrome, polished aluminum, and painted finish options?

Chrome-plated steel bumpers offer the classic mirror finish but require regular maintenance to prevent rust, especially in winter climates. Polished aluminum parts are lighter weight and won't rust, but may show scratches more easily and cost 20-30% more. Painted finishes are the most economical and can be color-matched to your truck, but lack the traditional shine many Cabover enthusiasts prefer. Chrome typically lasts 5-7 years with proper care, while quality painted finishes can last 10+ years.

Will I need help installing these parts, or can one person handle the job?

Bumper installation typically requires two people due to weight (50-80 lbs for front bumpers) and the need to align multiple mounting points simultaneously. Grilles and smaller trim pieces can usually be installed solo. Basic hand tools are sufficient for most installations, though an impact wrench speeds up the process. Budget 2-4 hours for bumper replacement, including removal of the old unit and adjustment of the new one. Professional installation typically runs $200-400 if you prefer not to DIY.
