the problem with the chevies is people are putting are running them in rigs that carry no wight..They seem to work best in 4runners,,a bit more weight..You can't put a spring from a heay truck and expect them to flex in a light rig..I have seen many perform very well,,rokdog on pirate has this set up,,flexes very nice,,I don't run blocks and I don't run long ass shackles and I run 36 irocks..I think there a advantange ,,set up right they will help slide your rig up on the rocks and help your tire to grab,,
I have no complaints but do see some rigs that don't don;t so so well under,,mnostly lighter rigs like I said..if your going to use a bigger heavy spring then you need a hevier truck,,think about it..
No flex,,??
they don't flex at all
