Have you ever noticed a difference in ride control when driving empty vs. driving fully loaded?

Your truck's factory suspension was designed as a compromise between capability and comfort. When hauling heavy loads, the rear springs can be pushed to the limit-resulting in excessive bounce, sagging ride height, and an overall feeling of instability.

With the simple addition of an Pacbrake Air Suspension Kits, you can distribute weight evenly to your tires, supporting any load without overtaxing your existing system.

  • Corrosion resistant roll plates
