The real question is, why shouldn't you? If you want to take your diesel truck's performance to the next level, installing and adding new mods can enhance the overall performance, feel, and efficiency of your truck. Plus, some of these power upgrades won't break the bank either. Although modifications tend to be pricey at first, they'll pay themselves off in the long run. For example, installing a larger fuel tank will help you avoid stops at the pump.
Then again, power upgrades can just be for the fun of it. Check out some of the mods we offer below.
There's a reason why air intakes are one of the most popular diesel truck mods: you feel a noticeable difference in power right away. It's a relatively simple upgrade, but it makes a massive difference to the overall feel of your truck.
Stock air intake systems tend to reduce engine noise while limiting performance. By installing a high-tech air intake system, you'll increase the amount of air coming into the engine, boosting your truck's performance.
DOUBLE your truck's fuel capacity.
Most stock diesel truck tanks range between 75L to 100L, but installing an upgraded fuel tank can increase your capacity to almost 200L of fuel. Sure, it's a mod you can't see from the street, but you'll appreciate it when your driving range increases and your stops at the pump drop in half.

Have you been taking your truck off-road often? Thinking about competing in off-road racing? There's nothing worse than getting kicked off the track. When you get a roll cage installed, you're essentially improving the safety of you, your passengers, and your truck. Not only will it help avoid injuries if you roll over, but it'll also help minimize the damage your truck takes if you end up in a ditch.
....and the million other things done to this beast.
Lift kits aren't only meant to make your truck look more like a beast — they'll give you room to add bigger wheels and tires while increasing your field of view. They're a real no-brainer for dieselheads.

Very happy with the work done at Cotton’s Custom Diesel. Appreciate their effort to get me up and running at a fraction of the cost the dealer was charging.

Amazing people and outstanding service! I came in to get a leveling kit installed on my Silverado, and they gave me a very competitive quote and did an excellent job. They’re genuine, down-to-earth folks who clearly love what they do—and it shows. Their shop is clean, organized, and fully equipped to handle just about anything. This will definitely be my go-to shop for any future upgrades I want for my rig.

These guys worked past closing on a Friday to get my truck done! Glad I drove almost 2 hours from home to get the work done. Well worth the drive.
