Designed for 2008–2025 Ford, GM, and Ram trucks, this system gives your diesel rig serious range without sacrificing your entire bed to get it. At 75 gallons, this tank strikes a smart balance between capacity and space. It fits neatly in both short and long bed trucks and doesn’t dominate your bed the way larger tanks can. You still have room for gear, tools, or even a fifth-wheel hitch, all while carrying enough extra fuel to save time, money, and hassle on the road. Trax 4 System Makes Fueling Effortless What really sets this setup apart is the TRAX 4 computer-controlled operating system. Instead of relying on manual switches or gravity-fed transfer lines, the TRAX 4 handles everything automatically. It monitors your main tank’s level and transfers fuel seamlessly as you drive, based on pre-set thresholds. That means no guesswork, no monitoring gauges constantly, and no need to pull over to activate anything. It's just smooth, consistent fuel management in the background while you focus on the road ahead. Additioanlly, durability is a core part of the design. The tank is built from 12- and 14-gauge aluminized U.S. steel, robot-welded for added strength, and finished in a tough black powder coat that holds up to weather, salt, and everyday abuse. Inside, the baffled structure minimizes sloshing, especially helpful when towing or driving on uneven terrain. And because it’s DOT-compliant and made in the USA, you’re getting peace of mind that it’s engineered and built to the highest standards. Installation is straightforward with all components and wiring included in the kit. And once it’s in, the system runs itself—making it perfect for anyone who wants more range without adding complexity to their truck.
