Frequently Asked Questions About International ProStar Parts & Bumpers

What Model Years Do International ProStar Bumpers Fit?

Our International ProStar bumpers are designed to fit model years 2008-2017. However, there are important differences between early ProStar models from 2008-2012 and later models from 2013-2017 due to changes in the mounting brackets. Always verify the OEM part number and model year before ordering. If you are unsure, our team can help confirm compatibility. Provide your truck's OEM number or call us with the specific model year and configuration.

What Is the Difference Between Steel and Aluminum International ProStar Bumpers?

Steel International ProStar bumpers typically weigh 85-120 pounds and provide maximum durability for heavy-duty applications. However, steel requires regular maintenance to help prevent rust. Aluminum ProStar bumpers typically weigh 40-60 pounds, which reduces front-end weight and may improve fuel economy. Aluminum also naturally resists corrosion but can show scratches more easily. Both materials meet DOT standards, so the better choice depends on whether you prioritize weight savings or maximum impact resistance.

Can I Install an International ProStar Bumper Myself?

International ProStar bumper installation typically takes 2-4 hours with basic tools, including a socket set and torque wrench. Having a helper is also recommended because of the bumper's weight. Before removing the original bumper, disconnect the fog lights and any sensors. One of the main challenges is supporting the bumper while aligning the mounting brackets. Many customers successfully complete the installation themselves, but professional installation is recommended if your ProStar has collision mitigation sensors or complex lighting because those systems may require proper calibration.

Will an Aftermarket International ProStar Bumper Affect My Warranty or Insurance?

Aftermarket International ProStar bumpers that meet or exceed OEM specifications typically do not void warranties, but you should always verify the specific warranty terms with your dealer. For insurance purposes, notify your provider about any modifications. Most DOT-approved aftermarket bumpers are accepted by insurance companies. Keep the purchase receipt and installation documentation as proof of the parts used and proper installation in case you need to make a future claim.

What International ProStar Bumper Finishes Are Available?

International ProStar bumpers are available in chrome, painted, powder-coated, and aluminum finishes. Chrome bumpers require monthly polishing to maintain their shine and help prevent pitting, especially during winter driving in areas that use road salt. Painted bumpers may come primer-ready for custom color matching or in standard black or white finishes. Powder-coated bumpers offer the best corrosion resistance but can be more difficult to repair if the finish is damaged. Many drivers operating in harsh climates prefer powder-coated or aluminum bumpers for longevity, while owner-operators building show trucks often choose chrome despite the additional maintenance.
