The rear suspension of my '57 Suburban needs a bit of help when loaded or when towing. I am thinking about getting either air shocks (with a small on-board compressor) or load-adjusting shocks (with the helper spring around them). I know how both type work, what they do, but I do not know how to choose which type I need... Is a kind of shocks better than the other for a specific use?
Can anyone help me?
