International S1700-S1900 Frame & Chassis

Frequently Asked Questions About International S1700-S1900 Frame & Chassis

What years and specific International S-Series models are these bumpers compatible with?

These bumpers are designed to fit International S1700, S1800, and S1900 models manufactured between 1979 and 2004. However, there are slight variations between early models (1979-1989) and later models (1990-2004) due to mounting bracket changes. Always verify your truck's exact year and OEM series before ordering, as some S1700 models with heavy-duty packages may require different mounting hardware. If your truck has been modified or has aftermarket components, measure the frame rail width and mounting hole spacing to ensure proper fitment.

Are these bumpers made from chrome-plated steel or stainless steel, and which material holds up better?

We offer both chrome-plated steel and polished stainless steel options. Chrome-plated steel bumpers provide a mirror-like finish at a lower cost but require regular maintenance to prevent rust, especially in areas with road salt. Stainless steel bumpers are more expensive initially but offer superior corrosion resistance and typically last 15-20 years with minimal maintenance. For trucks operating in coastal areas or regions with heavy winter salting, stainless steel is the recommended choice despite the higher upfront investment.

What tools and additional parts do I need for installation, and how difficult is it to install?

Installation typically requires basic hand tools including 3/4" and 7/8" wrenches, a socket set, and a torque wrench. Most installations take 2-3 hours for someone with moderate mechanical experience. You'll need new Grade 8 mounting bolts and we recommend replacing the rubber isolators if they're worn. Common challenges include rusted mounting bolts on older trucks and alignment issues if the frame has been bent. Some customers report needing to slightly enlarge mounting holes on 1979-1985 models. Professional installation typically costs $150-300 if you prefer not to DIY.

What's the difference between the 16-inch, 18-inch, and 20-inch bumper options?

The measurement refers to the bumper's front-to-back depth. The 16-inch is the standard OEM replacement size suitable for most applications. The 18-inch provides extra protection and is popular for vocational trucks or those with aftermarket grille guards. The 20-inch "Texas-style" bumper offers maximum protection and an aggressive appearance but may require relocation of front-mounted accessories like fog lights or air horns. Note that 20-inch bumpers can affect approach angles and may not be legal in all states due to projection limits.

Will these bumpers support mounting accessories like light bars, air horns, or tow hooks?

Yes, most of our S-Series bumpers come pre-drilled with standard mounting holes for common accessories. The center section typically has provisions for license plate mounting and small LED lights. Tow hook compatibility varies by model - standard bumpers support up to 10,000-pound rated tow hooks, while heavy-duty models can accommodate 15,000-pound hooks. For light bars over 30 inches or multiple air horns, we recommend our reinforced mounting brackets to prevent vibration and stress cracks. Always check the combined weight of accessories to ensure you don't exceed the bumper's load rating of 150 pounds.
