Question:

looking at your Pacbrake Alpha XD Air Bag Suspension Kit - Rear Axle - 7500lbs, for our 2024 Chevy Silverado 5500. Our truck not only squats but it has a good lean to the left side....does this system allow us to level the bed of this truck? I guess what I am asking is can we add lets say 100psi to the left bag and 60psi to the right bag for not only suspension help but for leveling purposes also?

Hi Tom!

The Pacbrake Alpha XD Air Bag Suspension Kit - Rear Axle - 7,500 lbs # PB77RV can indeed have the air bags filled to different amounts. This is why we regularly recommend air bags for RVs and work vehicles (especially vans). They are often heavier on one side due to equipment and other things. This one also includes two fill lines, so no extra parts will be needed to accomplish this.

Have you thought about a compressor as well? The Pacbrake Premium Paddle Valve In-Cab Control Kit w/ Analog Gauge and Compressor - Independent Fill # PB89VV would be a good option as it can fill each bag individually. I think it would serve you very well.

Is this a work truck and/or what are you typically carrying?
