Have you ever noticed a difference in ride control when driving empty vs. driving fully loaded in your 2007-2024 Sprinter? Your van'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 XD 7500 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 7" Alpha XD 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 kit comes with corrosion-resistant roll plates, precision laser-cut powder-coated steel brackets, grade 5 plated hardware, airline, and all accessories required for a perfect bolt-on installation. With Pacbrake, you can level your van’s stance and eliminate sag, sway, and bottoming out while providing added support for a smooth, stable, and safe ride.
