Frequently Asked Questions About Peterbilt 389 Frame Steps & Acc.

What are frame steps and why does my Peterbilt 389 need them?

Frame steps mount to the truck's frame rail behind the cab or near the fuel tanks and fairings, giving drivers a secure foothold for climbing up to check fluids, clean windows, access the fifth wheel, or reach the top of the fuel tanks. They're a practical accessory for everyday cab-over-frame access on a 389.

Will these steps fit my specific frame rail width and fuel tank setup?

Fitment can vary depending on your truck's frame rail spacing, fuel tank size, and whether you have factory or aftermarket fairings. Most listings note the specific frame width or tank diameter they're designed for, so double-check those measurements against your truck before ordering, and reach out to us if you're unsure which option matches your configuration.

What materials and finishes are available, and how do they hold up?

Frame steps are commonly offered in aluminum, steel, or stainless steel, with finishes ranging from raw or polished aluminum to chrome-plated or powder-coated steel. Stainless and chrome options tend to resist corrosion and clean up easier, while raw aluminum is lighter but may require more upkeep to keep looking new. Choose based on how much maintenance you're willing to do versus the look you want.

Are these steps easy to install, and what hardware or tools are needed?

Most frame steps bolt directly to existing holes in the frame rail or attach with brackets and mounting hardware included in the kit. Basic hand tools are typically all that's required, though some brackets may need drilling if your frame doesn't have pre-existing holes. If you're not confident with the install, a truck shop can usually mount them quickly.

Do frame steps affect ground clearance or interfere with other components?

Properly sized frame steps are designed to sit close to the frame rail without hanging low enough to cause clearance issues on most road conditions. That said, always check for interference with air lines, fuel lines, battery boxes, or exhaust components in your specific setup before finalizing placement, since aftermarket fairings and tank sizes can change available space.
