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.

How do I measure my steps and/or tank?

If your truck already has fuel tank steps, simply measure the length of the existing step. Be sure to measure the step only, from inside the two tank step brackets. Also measure the diameter of your fuel tank to determine what size brackets you need. (see top photo)

If your truck does not have fuel tank steps, measure the distance between the tank hangers (see bottom photo). The tank steps and brackets can be mounted on the outside of the hangers or on the inside, so you have two choices of length. For inside mounting, you will need to subtract 3/8" from your measurement.

How do I measure my steps and/or tank?
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.
