Hey Guys, firstly I should say I did do some searching on this already. It seems like the cause is most likely shocks, but I want to make sure I hit everything while I am down there.

I bought my 2500HD '06 used with 150k miles on it. I immediately noticed that while driving on the freeway it porpoises a lot when hitting gentle rises/falls in the pavement. Then, this last weekend I took it down to southern utah and traveling offroad was near unbearable. The entire truck would shake violently when going over bumps/rocks/crevices unless I took it extremely slow. Needless to say the washboard areas were painful.

So, I was looking at the 4600 bilsteins as a first step, but I was wondering if I should tackle anything else while I have the truck on the lift.

Thanks in advance!
