The industry preference these days are aluminum tanks, which are great for durability against both rust and impact damage. However, aftermarket Freightliner parts that have been custom fitted for the makes and models currently on the road can often be pricey and those that haven't might not even work with your rig. These factors may tempt you to just go back to the OEM for direct purchase, but rest assured, OEM parts are always priced well above the industry standard for custom parts.

So, what's the solution? Well, a warranty period that lasts long enough for you to get a real feel for the performance of your new fuel tank is a must. Here at 4-State, we offer a two year money back guarantee on our ALTTEC Freightliner fuel tanks. That's how sure we are that they will perform above and beyond expectations.

In addition to the coveted aluminum construction on our fuel tanks, they are manufactured to mimic OEM construction, which is essential for compatibility. Our designs come complete with filler necks and plumbing modeled after the Freightliner brand.

On average, we have all standard sizes in stock and ready to be shipped or picked up the same day. However, if you're after a custom-built tank, we can accommodate that too, with just 45 days lead time.

Our exclusive fuel tank manufacturer, ALTTEC, has over 20 years of industry experience in aluminum fuel tank manufacturing for semi-trucks and reefer trailers. They are certified and approved by the FMSCA in North America. In other words, the highest level of trustworthy a product manufacturer can get!
