I have a good friend who is interested in doing some suspension mods on his late model Chevy truck. I don't know the model. He asked me to help him do some research into products, since I'm more of a car guy than he is. I have no idea on that score. Anybody got any ideas on where to look, where to start looking?

Thanks. Sorry to enter the word "Chevy" into the forum.
