Ok So I got this truck from my father in law. It is a 2000 Silverado excb with 230k miles. He replaces the shocks on it and the ride is rough as heck. I think he put the stiffed things he could find. I am about to put a set of 22's on it with 305-40's. My question is what is a good shock that I can get that will not brake the bank but have a much better ride. Is there one that will also work with a 2/4 when I do that or will i need new shocks all over again?
