Frequently Asked Questions About International 4700-4900 Frame Steps & Acc.

Will these frame steps fit my specific International 4700 or 4900 model year?

Most frame steps are designed to fit International 4700 and 4900 models from 1989-2017. However, there can be variations based on cab configuration (regular vs. extended) and whether you have air or spring suspension. We recommend checking the product description for specific year ranges or calling us with your VIN to confirm compatibility. Some steps are universal while others are year-specific, particularly for models with DT466 engines versus newer MaxxForce engines.

What's the difference between aluminum and steel frame steps, and which should I choose?

Aluminum steps are lighter (typically 15-20 lbs vs. 30-40 lbs for steel), won't rust, and are easier to polish for a show-truck appearance. Steel steps are more affordable and extremely durable but require regular maintenance to prevent rust. If you're in a high-salt area or want a maintenance-free option, go with aluminum. For heavy-duty work applications where cost is a concern, steel steps work great with proper care.

Do I need to drill holes in my frame to install these steps?

Many frame steps use existing frame holes and bolt patterns, requiring no drilling. However, some models may require 2-4 new holes depending on your truck's configuration. Each product listing specifies if drilling is required. Most installations take 1-2 hours with basic hand tools. We always recommend using grade 8 bolts and applying anti-seize compound for easier future removal.

What step width and tread pattern works best for work boots and safety?

Look for steps that are at least 6 inches wide with aggressive tread patterns or grip tape surfaces. Diamond plate provides good traction when clean but can be slippery when wet or muddy. Expanded metal or serrated bar grating offers superior grip in all conditions. For maximum safety, choose steps with raised edges to prevent foot slippage and consider adding LED marker lights for nighttime visibility.

Can I mount accessories like tool boxes or air tanks on these frame steps?

Many frame steps are designed with mounting points for accessories. Heavy-duty steps with 3/8" or thicker platforms can typically support tool boxes up to 100 lbs. Some models include pre-drilled holes for common accessories. Always check the weight rating in the product specs. For air tanks, ensure the step bracket doesn't interfere with your brake chambers or suspension components. Combination step-and-battery box units are also available for space-saving installations.
