Is your rig ready for an upgrade? If so, you’re in luck! An array of options are available when it comes to choosing aftermarket upgrades for your semi-truck.

Whether you want to modify your engine, brakes, or in-cab options, let’s take a look at what’s out there so that you can make the best choice for your specific needs.

If you’re looking to boost your rig’s efficiency and performance, a hydraulic tank is a great way to do so. You can extend the life of your semi-truck’s engine with the help of a hydraulic tank, minimizing downtime or expensive repairs. Pairing a high-efficiency hydraulic tank with a sleek-looking headache rack can save space, time, and, ultimately, money.

Be as prepared as possible with a battery box. Having an extra set of batteries for your truck is crucial when you need them the most. A variety of sizes and styles are available to fit your particular amount of available space.

Cab racks are another way to upgrade that come in a wide variety of customizable options for your rig. Internal shelves, chain hangers, and your choice in the number of doors allow you to tailor this pick to your specifications. Cab racks are essential for storing the items you need to keep secure and free from damage—think inclement weather conditions that are unavoidable when you’re in for a long haul. Accessibility and size are key to narrowing down the search to the cab rack that’s best for you.

Choosing a new, updated fender for your semi-truck is an additional way to boost your truck’s style and performance. Whether you choose a fender that is made of stainless steel, polymer, or aluminum, each offers their own benefits. Durability and cost are the top two factors to consider when you’re trying to decide what type of fender will work best for you on the road.
