Deter Heat Damage with an Aftermarket Heat Shield

Exhaust stack heat shields protect not only your truck but also you. These plates cover the hot surfaces of your semi’s exhaust system, keeping heat under control and away from nearby parts, paint, and people.

Why Use a Heat Shield?

Every time you run your rig, your exhaust stack can get dangerously hot. Heat shields deflect that extreme heat, helping prevent burns, melted components, or even fires. They also improve aerodynamics and give your exhaust a cleaner, more finished look.

What Happens If You Drive Without One?

Technically, your truck can run without a heat shield—but it’s not smart. Without protection, heat can warp nearby parts, damage your paint, or even crack your DPF elbow. If your existing heat shield falls off, replace it fast to avoid long-term damage.
