International Polishing

Frequently Asked Questions About International Truck Polishing

What grade of stainless steel are International polished bumpers made from, and will they rust or tarnish over time?

Most quality International polished bumpers are manufactured from 304-grade stainless steel, which offers excellent corrosion resistance. However, exposure to road salt, magnesium chloride, and harsh chemicals can cause surface rust or pitting if not properly maintained. We recommend washing your bumper regularly during winter months and applying a stainless steel polish every 3-4 months to maintain the mirror finish. Bumpers mounted in coastal areas may require more frequent maintenance due to salt air exposure.

Which International truck models and years are compatible with these polished bumpers?

Polished bumpers are available for International ProStar (2008-2017), LoneStar (2009-2017), 9900i (1995-2007), 9400i (1995-2007), and LT Series (2018-present). However, specific mounting brackets and bolt patterns vary between model years. For example, 2008-2012 ProStar bumpers use different mounting points than 2013-2017 models. Always verify your exact truck model, year, and whether you have an aero or standard hood configuration before ordering, as these factors affect fitment.

How difficult is the installation process, and what tools or modifications are required?

Installation typically takes 2-4 hours and requires basic hand tools including socket wrenches, torque wrench, and potentially a drill for auxiliary light mounting. Most polished bumpers are direct bolt-on replacements, but some models may require trimming air dam brackets or relocating fog light wiring. Two people are recommended for installation due to bumper weight (typically 75-150 lbs). Professional installation may be preferred if you need to relocate air lines, install additional lighting, or integrate bumper-mounted accessories.

What finish options are available, and how do they differ in appearance and maintenance?

The most common finishes are mirror polish (highest shine but requires most maintenance), brushed finish (hides minor scratches better), and chrome-plated steel (brightest finish but can peel if damaged). Mirror polished stainless requires buffing every 2-3 months to maintain showroom appearance, while brushed finishes can go 6+ months between polishing. Some bumpers also offer powder-coated end caps or accent pieces in black or body-color match options.

Can I mount accessories like light bars, fog lights, or air horns on polished bumpers?

Yes, most polished bumpers come with pre-drilled mounting points for standard accessories. Common configurations include dual rectangular fog light cutouts, center light bar mounting holes, and air horn brackets. However, drilling additional holes for custom accessories is possible but requires stainless-specific drill bits and careful work to avoid stress cracks. Many bumpers accommodate popular light brands like Rigid Industries or KC HiLites using standard mounting patterns. Always check weight limits for bumper-mounted accessories, especially for air horn setups.
