Frequently Asked Questions About Peterbilt 388 Frame Steps & Acc.

What years and models are these frame steps compatible with?

Most frame steps in this category are designed specifically for Peterbilt 388 models from 2006-2015. However, compatibility can vary based on your truck's configuration, including wheelbase length and exhaust setup. Always verify the specific part number against your VIN or contact our support team with your truck's year and specifications to ensure proper fitment.

Are these frame steps made from aluminum or steel, and which is better for my application?

We carry both aluminum and steel frame steps. Aluminum steps are lighter (typically 40-50% less weight than steel) and won't rust, making them ideal for weight-conscious operations and coastal areas. Steel steps are more economical and extremely durable for heavy-duty use but require regular maintenance to prevent rust. Most aluminum options feature diamond plate or punched hole designs for superior grip.

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

Most frame steps in our selection are designed as bolt-on applications using existing frame holes or mounting brackets. Installation typically takes 1-2 hours per side with basic hand tools. Some universal options may require drilling, which will be clearly noted in the product description. We recommend having the installation done by a qualified technician if frame modifications are needed.

What's the difference between cab-mounted and frame-mounted steps?

Frame-mounted steps attach directly to your truck's frame rails and are more stable for heavy use, making them ideal for vocational trucks or frequent climbing. Cab-mounted steps attach to the cab structure and move with the cab, which some drivers prefer for consistency. Frame-mounted options typically offer more step positions and are easier to customize for different driver heights.

How do I maintain chrome versus powder-coated frame steps?

Chrome steps require regular polishing with chrome-specific cleaners to maintain their mirror finish and prevent pitting, especially in winter conditions with road salt. Powder-coated steps need only soap and water cleaning and are more resistant to chips and corrosion. Chrome provides a classic look but demands more upkeep, while powder coating offers long-term durability with minimal maintenance.
