2009 S bucks when taking whoops

I have a 2009 S with stock podium shocks and King Progressive springs (not sure exactly which ones as they came with it when I bought it). On my most recent ride I had some of the others following me comment that my rear tires bounce off the ground a lot when I am hitting whoops. I didn’t realize that was happening, but I knew that the rebound was pretty harsh on the rougher stuff. I took a quick look a the podiums and there appears to be an adjustment screw on them. Is that for rebound like on a quad? I have ready many of the post on here about what are the best shocks, but I am hoping that I can just adjust my podiums or maybe have them revalved? I know the King springs are good, but what do you guys suggest I do? I would like to get a smoother ride over the rough stuff if possible without having to spend $1000s.

Thanks.
