Have you ever noticed a difference in ride control when driving empty vs. driving fully loaded in your GM 1500 Duramax? Your 1500'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 a Pacbrake Alpha HD Air Spring / Air Suspension Kit, you can distribute weight evenly to your tires, supporting any load without overtaxing your existing system.

Pacbrake Heavy Duty Double Convoluted Alpha HD Air Spring / Air Suspension Kits are the only air springs (or air helper springs) on the market with one piece aluminum end caps and 20 support wires giving you maximum strength and durability! Each Alpha HD Double Convoluted Air Spring / Air Suspension Kit is equipped with corrosion resistant roll plates, precision laser cut powder coated steel brackets, grade 5 plated hardware, airline and all accessories required for the perfect bolt on install.

With Pacbrake you can level your truck's stance and eliminate your vehicle's sag, sway and bottoming out while providing added support for an overall smooth and safe ride.
