Frequently Asked Questions About International 9300/9370 Frame Steps & Acc.
What year models do these frame steps fit, and are there differences between 9300 and 9370 mounting points?
These frame steps are designed to fit International 9300 and 9370 models from 1987 through 2017. While the 9300 and 9370 share similar frame rails, the mounting points can vary slightly depending on your specific configuration. Models with set-back front axles may require different bracket positioning. We recommend checking your frame rail width (typically 34" outside-to-outside) and measuring the distance from your cab to the first crossmember before ordering.
What materials are these steps made from, and how do they hold up to road salt and weather?
Most frame steps in this category are constructed from either 304 stainless steel or heavy-duty aluminum. Stainless steel options offer superior corrosion resistance and typically feature a mirror polish or brushed finish that maintains its appearance even in harsh winter conditions. Aluminum steps are powder-coated for durability but may show wear faster in extreme salt environments. Both materials are significantly more durable than the factory plastic steps and can support up to 500 pounds.
Do I need to drill new holes in my frame, and what tools are required for installation?
Most aftermarket frame steps utilize existing frame holes whenever possible, though some applications may require drilling 1-2 additional mounting holes. Installation typically requires a drill with metal bits (if drilling is needed), a socket set, and approximately 1-2 hours per side. Many drivers report that aligning the brackets can be challenging on trucks with aftermarket fuel tanks or custom battery boxes, so test-fitting before final installation is recommended.
What's the difference between single-step and double-step designs, and which is better for my application?
Single-step designs mount closer to the cab and work well for day cabs or trucks with limited frame space. Double-step configurations provide an intermediate step, making cab entry easier and safer, especially beneficial for older drivers or those with knee issues. Double steps typically extend 6-8 inches further from the frame. Consider your cab height, physical needs, and any frame-mounted accessories when choosing between styles.
Will these steps interfere with my DEF tank, tool boxes, or other frame-mounted equipment?
Frame step compatibility with DEF tanks and tool boxes varies by truck configuration. Pre-2010 models generally have more mounting flexibility since they lack DEF systems. For 2010 and newer trucks, measure carefully around your DEF tank location. Most steps can be adjusted forward or backward by 2-3 inches using alternate mounting holes. Battery box interference is common on trucks with relocated batteries - in these cases, shorter single-step designs or offset mounting brackets may be necessary.
