After the first drive in the truck over 10 miles on the way to work this morning, I've decided the shocks are probably a bit too worn to leave the way they are. Any recommendations for street shocks which are relatively inexpensive? I'm not too sure what bilsteins run for these trucks, but I'm aware they are a pretty good company. My brother installed Monroe? shocks on his '02 Tahoe and says they work fine. What are your opinions?
