Peterbilt 567/579 Frame Steps & Acc.

Frequently Asked Questions About Peterbilt 567/579 Frame Steps & Acc.

What are frame steps and why would I need to replace or upgrade mine?

Frame steps are the step assemblies mounted to the truck frame that provide a stable point for climbing in and out of the cab or accessing components mounted along the frame rail. Over time, steps can wear out, crack, rust, or bend from road debris and daily use, and replacing them with a properly fitted step restores safe, reliable access to your Peterbilt 567 or 579.

Will these frame steps fit my specific Peterbilt 567 or 579 configuration?

Frame step fitment can vary based on frame rail height, wheelbase, and whether your truck has factory or aftermarket brackets already in place. It is important to check the listed specifications and measurements for each step against your truck's setup before ordering, and to reach out to our team if you are unsure about compatibility with your particular configuration.

What materials are these frame steps made from, and how do they hold up to weather and road grime?

Frame steps in this category are typically offered in aluminum or steel, sometimes with diamond plate or non-skid surfaces for added traction. Aluminum options resist corrosion well and stay lighter, while steel versions offer added durability under heavy use. Finish options such as polished, painted, or powder-coated surfaces affect both appearance and long-term resistance to rust and grime buildup.

What mounting hardware is included, and is installation straightforward?

Most frame steps come with the necessary mounting brackets and hardware for a direct bolt-on installation to the existing frame mounting points, though some applications may require minor drilling or bracket adjustment. Installation generally does not require specialized tools, but we recommend reviewing the included instructions and comparing bolt patterns to your truck before starting the job.

How do I keep my frame steps looking good and functioning safely over time?

Regularly cleaning off road salt, mud, and grime helps prevent corrosion and keeps step surfaces from becoming slick. For polished aluminum steps, periodic polishing will maintain shine, while painted or powder-coated steps benefit from occasional inspection for chips or scratches that could lead to rust. Checking mounting bolts periodically for tightness also helps ensure the step stays secure and safe to use.
