Description

ALUMINUM REPLACEMENT STEP FOR PETERBILT FUEL TANKS

Sold individually. Side brackets not included. Does include stainless steel hardware.

  • Choose from lengths listed, and width of 4-3/4" (top) OR 7" (bottom)
  • Replacement for an existing top or bottom fuel tank step
  • Made in USA with American-made materials
  • Heavy duty riveted end plates --> stronger & more durable than welded or folded ends. The end-plate brackets distribute weight along 3" on each side, and the rivets allow just enough flex to prevent cracking. Using rivets has been proven to be a superior fastening method versus welding in many industrial and automotive applications.
  • Because our steps are bolt-on, they can easily be replaced if damaged again.

HEAVY-DUTY VERSION --- Recommended on ALL steps 35"+, Required on ALL steps 42"+. Includes 3/16" aluminum plate riveted to front edge of step for greater strength. This option eliminates the steps from cracking and bending in the middle.

Select length you need, or closest to it (measure length of step only, not including the side brackets).

2-Day Air Express shipping exception: kits over 47-1/4" (1200mm) can ONLY be shipped ground, NOT air.

Frequently Asked Questions

Here are the most common questions and answers about our products. Call or text if you have another question not listed here.

What is the difference between standard and heavy duty?

Heavy duty steps are reinforced with a 3/16" thick aluminum plate riveted to the front edge. This makes the steps significantly stronger. We always recommend the heavy duty steps - unless they're for light use, like on the passenger side.

What is the difference between standard and heavy duty?
Is this part in stock? When can you ship it?

Yes, all of our parts are in stock and ship from our Reno, NV shop within 1 to 2 days.

Can I return this if it doesn't fit?

Yes. You are responsible for the cost of return shipping, so read the full description and double check the part numbers, measurements, and photos to ensure you are ordering the correct part.

Do you make the products on your website?

Yes. We make the products we sell - in Reno, NV, with high-quality American-made materials. Even the rivets we use on our steps are made in the USA.

Do you offer express shipping?

Yes, except on a few oversize items. You can select 2-day express shipping at checkout. Keep in mind that does not include our processing time of 1-2 days. So express shipping will take 3+ business days after you order.

Can I call to place an order over the phone?

You can, but honestly, the website is the easiest and fastest way to place your order.

    Reliable, intuitive, and surprisingly affordable. I use Fleetassist for my personal car and it’s been a game changer. Trip overviews are crystal clear and the app works flawlessly.

    I run a small delivery business and needed a system that’s both tax-compliant and easy to manage. Fleetassist delivers exactly that. The installation was quick, and the live tracking is spot-on.

    As a self-employed electrician, I’m on the road a lot. With Fleetassist, I no longer have to think about logging my trips — it’s all done automatically. And the customer support? Top-notch.
