I have a 04 silverado and i was wanting to know if anybody has seen this or road in a truck that had these suspensions systems. I was thinking of getting these suspension upgrade in my truck but dont know if it will help my truck perform better. How does it ride with these suspension systems? The system i'm talking about is the 4-link air suspension with air bags for the rear and shockwave airbags with lower and upper control arms for the front. The reason i'm looking into this suspension upgrade is because when i floor my truck the tires just spin. If thier is a different solution to make the truck hook up and go let me know.
